Description

Technical Field

[0001] The present invention relates to the technical field of phosphogypsum production, and particularly relates to a phosphogypsum hole punching and inserting tooling equipment. Background Art

[0002] Phosphogypsum is the main by-product of the wet-process phosphoric acid process, mainly composed of gypsum, containing impurities such as water-soluble phosphorus, fluorine, and unreacted phosphate rock, with strong acidity. Disposing of it randomly will pose a serious threat to the ecological environment. At present, phosphogypsum is mainly used in fields such as cement retarders, gypsum building materials, and ecological restoration. However, it has long faced the dilemmas of long harmless treatment and resource utilization processes, high costs, and low product added value, and has a huge pressure for large-scale consumption.

[0003] In response to the call for actively addressing the drawbacks of phosphogypsum production, our company has built a "one line, two products" phosphogypsum production line with an annual processing capacity of 100,000 tons. The type II anhydrous gypsum powder produced by this production line is widely used in fields such as plastic and rubber fillers, mine filling, and building materials.

[0004] The semi-dry autoclaving method in the above production line, the existing semi-dry autoclaving method, that is, the usual semi-dry method, refers to uniformly mixing powdery or smaller particle-sized gypsum raw materials mixed with powder with a crystal conversion agent solution. After mixing, the overall moisture content of the raw materials generally remains in a semi-dry state within 20%. The semi-dry state of the gypsum raw materials is directly fed into a crystal conversion device and undergoes crystal conversion or granulation under a saturated steam medium with a certain pressure and then crystal conversion.

[0005] The above-mentioned gypsum mixed raw materials are generally transported to a feeding trolley by a feeding belt. In this process, the gypsum mixed raw materials are directly put into the bin of the feeding trolley, and the gypsum mixed raw materials are in a flat state in the bin. After being transported to a designated position by the feeding trolley, subsequent steam autoclaving treatment, etc. are carried out. However, since the gypsum mixed raw materials are in a flat state in the feeding trolley, when carrying out subsequent steam treatment processes, the contact surface between the steam and the gypsum mixed raw materials is basically the same as the upper surface of the gypsum mixed raw materials in the feeding trolley, and this contact area is small; in this small-area contact form, the gypsum mixed raw materials cannot be evenly heat and mass transferred by the steam, reducing the reaction rate and conversion rate. At the same time, in order to accelerate the reaction rate and increase the conversion rate, the conventional process needs to add corresponding granulation equipment and return material operations, which increases equipment investment and energy consumption.

[0006] Therefore, we propose a phosphogypsum hole punching and inserting tooling equipment to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to solve the problems in the prior art and to propose a phosphogypsum drilling and drilling equipment, which realizes the drilling process of the mixed raw material by rotating and lifting the drill rod, thereby increasing the contact area between the mixed raw material and water vapor and achieving uniform heat transfer between the mixed raw material and water vapor.

[0008] In order to solve the above problems, the present invention provides the following technical solutions:

[0009] A phosphogypsum drilling and drilling equipment includes several groups of drilling components that can perform lifting movements. Each group of drilling components has several drill rods, and the drill rods can rotate about their own axes. When the mixed raw materials are located within the range of the active path of the drill rods, the drill rods can perform a similar self-rotation movement toward the mixed raw materials to achieve drilling processing of the mixed raw materials.

[0010] As a further solution of the present invention, the rotation speed of the drill rod when it moves upward is greater than the rotation speed when it moves downward, so as to expand the diameter of the hole.

[0011] As a further solution of the present invention: the equipment also includes a frame for installing a punching assembly, the punching assembly includes a transmission box movably arranged on the frame in a vertical direction, a plurality of the drill rods are rotatably arranged at the bottom of the transmission box, and the drill rods are arranged in a vertical direction, a first drive source is fixedly provided on the top of the transmission box, and a transmission connection is achieved between the first drive source and the drill rods through a transmission gear assembly inside the transmission box.

[0012] As a further solution of the present invention: the equipment also includes a locking mechanism for ratcheting the transmission box during the rising process, the locking mechanism includes a limit strip provided on the frame and a swing arm rotatably provided on the outside of the transmission box, the limit strip is arranged in the vertical direction, and the limit strip is provided with a plurality of jacks at equal distances along its length direction, the swing arm is arranged relative to the limit strip, the swing arm has a latch portion close to the limit strip and a counterweight portion away from the limit strip, and a counterweight portion is provided on the outside of the transmission box within the movable range of the counterweight portion. The stop rod is in a state of conflict with the counterweight to limit the latch portion to remain in a state facing the limiting strip, so that the latch portion has a first working state in which it is inserted into the insertion hole and a second working state in which it conflicts with the non-insertion hole portion of the limiting strip; when the swing arm moves upward with the transmission box, the latch portion switches back and forth between the first working state and the second working state, and the counterweight portion moves away from the stop rod; when the swing arm moves downward with the transmission box, the latch portion is in the first working state and conflicts with the bottom wall of the insertion hole, and the counterweight portion conflicts with the stop rod.

[0013] As a further solution of the present invention: the locking mechanism also includes a third driving source arranged outside the transmission box, and the execution end of the third driving source can drive the swing arm to rotate so that the pin portion of the swing arm moves out of the socket.

[0014] As a further solution of the present invention: a guiding slope is provided on the top of the latch portion, and the heights of both ends of the guiding slope gradually increase from the end of the swing arm close to the limiting strip to the end away from the limiting strip.

[0015] As a further solution of the present invention: a pad for supporting the latch portion is fixedly provided on the bottom wall of the socket, and the pad is arranged horizontally.

[0016] As a further solution of the present invention: the frame has four evenly distributed support rods, the four ends of the transmission box are respectively slidably installed on the four support rods, the limiting strips are set as four groups and are respectively arranged on the four support rods, the swing arms are set as four groups and are respectively arranged at the four ends of the transmission box, each group of swing arms is adapted to the corresponding limiting strips, so that the locking mechanism constitutes a surface locking of the transmission box.

[0017] As a further solution of the present invention: an adapter bracket is fixedly provided at the end of the transmission box, and two groups of guide wheel groups arranged at right angles are fixedly provided on the adapter bracket, and the two groups of guide wheel groups are respectively rollingly connected to the adjacent two sides of the support rod, and the guide wheel group includes a plurality of rollers that are rotatably provided on the adapter bracket, and the plurality of rollers are arranged along the length direction of the support rod, and the rollers are rollingly connected to the side of the support rod.

[0018] As a further solution of the present invention: the equipment also includes a second driving source for driving the punching assembly to perform lifting and lowering movements. The second driving sources are arranged in four groups and are evenly distributed on four support rods, and the execution end of the second driving source is connected to the adapter bracket.

[0019] As a further solution of the present invention: the drill rods are provided in plurality, and the plurality of drill rods are evenly distributed on the transmission box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the design of multiple sets of lifting punching components and the drill rod, the lifting action of the drill rod is realized. When the mixed raw materials move within the moving path range of the drill rod, the descending action of the drill rod can achieve efficient and uniform punching of the mixed raw materials, enabling the punched mixed raw materials to have multiple sets of holes. During the subsequent steam process, uniform heat and mass transfer of steam is achieved by relying on the formed holes, significantly improving the reaction rate and conversion rate. At the same time, the subsequent production process is simplified, equipment investment and energy consumption are reduced, batching time is shortened, and production capacity is increased. Further, through the design of the self-rotation of the drill rod, the drill rod can rotate self during the descending process. From a fixed position on the drill rod, this fixed position makes a helical motion under the combined action of descending and rotation. Based on the motion characteristics of the helical motion, smooth and stable punching of the mixed raw materials can be achieved, and it will not be blocked by the descending resistance generated due to a large number of punchings. In summary, adding the action of the self-rotation of the drill rod during the descending process of the drill rod can not only achieve uniform heat and mass transfer of steam, significantly improve the reaction rate and conversion rate, but also dynamically adapt to the material characteristics, avoid jamming, and significantly improve the operation continuity and hole position quality.

[0022] 2. After the drill rod rotates self and descends to the specified position, the drill rod still needs to maintain the self-rotation action during the upward movement, and the rotation speed during the upward movement needs to be greater than that during the downward movement. The function of the higher rotation speed during the upward movement here is as follows: Based on the same unit length of the drill rod, the higher the rotation speed of the drill rod, the greater the amplitude of its swing. Therefore, on the premise of achieving holes with a certain diameter in the aforementioned downward operation, by increasing the rotation speed of the drill rod during the upward movement, the swing amplitude can be increased. The increase in the swing amplitude will perform an expanding diameter treatment on the holes completed by the downward operation. This expanding diameter treatment can further increase the contact area between the mixed raw materials and steam, and improve the reaction rate and conversion rate. Compared with relying solely on the self-rotation state of the drill rod during the downward movement, in this state, the present application also adds a state where the rotation speed during the upward movement is greater than that during the downward movement, enabling the drill rod to adaptively switch between the two states during the upward and downward movements, and achieving the punching treatment with the maximum diameter of the holes under the condition that the equipment resources such as the length of the drill rod and the driving source are constant.

[0023] 3. The modular transmission box structure integrates the driving source and the gear transmission system, making the equipment both compact and expandable. The vertically arranged drill rod cooperates with the top drive design, optimizing the force transmission path and facilitating the synchronous control of multiple drill rods.

[0024] 4. The ratchet type locking mechanism automatically realizes step-by-step locking during the lifting process through the gravity-counterweight dual-state switching mechanism. This design not only ensures the operation safety but also reduces energy consumption through mechanical self-locking, and is applicable to the failure state during the lifting process and the frequent start-stop working conditions.

[0025] 5. Adding a third drive source realizes active control of the swing arm, so that the locked state can be controlled and released. This improvement breaks through the limitations of traditional purely mechanical locking and provides a hardware foundation for the intelligent upgrade of the equipment.

[0026] 6. The wedge-shaped design of the guide slope of the latch significantly reduces the risk of the locking mechanism getting stuck. Its gradual height not only ensures insertion reliability, but also improves the fault tolerance of the equipment through the self-centering of the slope.

[0027] 7. The support pad design on the bottom wall of the socket cleverly solves the problem of pin impact. The horizontal arrangement not only disperses the force but also facilitates maintenance and replacement, effectively extending the service life of the locking mechanism.

[0028] 8. The evenly distributed design of the four sets of surface locking mechanisms upgrades point contact to surface constraint, which enables the transmission box to obtain stable constraint in three-dimensional space. It is particularly suitable for large-tonnage drilling operations and significantly improves the anti-eccentric load capability.

[0029] 9. The right-angle guide wheel group adopts multi-roller distributed contact, which not only ensures the smoothness of lifting and lowering, so that the punching component only has the freedom of lifting and lowering, but also replaces sliding friction with rolling friction, which reduces the energy consumption of the transmission box.

Detailed implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] Based on a series of drawbacks generated by gypsum raw materials in the semi-dry autoclaving process in the prior art, we propose a phosphogypsum production process, adding a punching step in the semi-dry autoclaving process to enable the gypsum mixed raw materials to come into large-area contact with the steam in the subsequent steps. The specific steps of one operation are as follows:

[0043] Step 1: Pretreat the gypsum raw materials (remove impurities and adjust the physical properties of the gypsum raw materials to meet the autoclaving requirements).

[0044] The specific operation of this step is:

[0045] Crushing and screening: Crush the massive phosphogypsum into particles of 1 to 5 mm, and screen out oversized particles and impurities.

[0046] Pre-drying: Control the moisture content to 10% to 15% (semi-dry state) to avoid excessive moisture affecting the autoclaving efficiency.

[0047] Water washing: Remove soluble phosphorus and fluorine (such as H3PO4, NaF).

[0048] Neutralization: Add lime (CaO) to adjust the pH to 6 to 7 to reduce the corrosion of the equipment by acidic impurities.

[0049] Step 2: Add additives to the pretreated gypsum raw materials to form mixed raw materials.

[0050] The specific operation of this step is:

[0051] Add several kinds of additives to the gypsum raw materials processed in Step 1 and mix them evenly. The additives can be crystal form regulators (such as citric acid, tartaric acid) to control the crystal form of type II anhydrous gypsum; the additives can be reinforcing agents (such as glass fiber, silica fume) to improve the strength of the finished product.

[0052] Step 3: Use a punching and inserting tool to punch the mixed raw materials to form multiple holes in the mixed raw materials.

[0053] The specific operation of this step is as follows:

[0054] Move the punching and inserting tool with a drill rod towards the mixed raw materials until the drill rod is inserted into the mixed raw materials, forming holes in the mixed raw materials to expand the contact area between the mixed raw materials and air.

[0055] Step 4: Perform autoclaving treatment on the mixed raw materials with multiple holes;

[0056] The specific operation of this step is as follows:

[0057] Place the mixed raw materials that maintain the hole shape in a closed container, and then inject steam into the closed container. The steam injection stage is divided into: 1. Heating stage: Heat up to 120 - 130 °C at a rate of 0.5 to 1 °C / min to avoid cracking of the materials caused by sudden temperature rise; 2. Constant pressure control: Maintain the steam pressure at 0.3 to 0.5 MPa to ensure full penetration of the steam. Keep it for 4 to 8 hours according to the thickness and purity of the raw materials. Slowly release the steam at the end of the reaction and drain the condensed water to prevent pulverization of the materials caused by sudden pressure drop.

[0058] During this process, since the surface area of the mixed raw materials exposed to air is expanded, when they are placed in a closed container while maintaining the hole shape, the contact area with the subsequently injected steam will also increase. Compared with the conventional contact in the prior art, the holes formed by punching and inserting in this application enable uniform heat and mass transfer of steam, greatly improving the reaction rate and conversion rate; at the same time, it simplifies the subsequent production process (no need for water granulation and no return materials), reduces equipment investment and energy consumption, shortens the batching time and increases production capacity.

[0059] Step 5: Perform drying and grinding treatment on the autoclaved mixed raw materials.

[0060] The specific operation of this step is as follows:

[0061] 1. Drying: Use a paddle dryer or a flash dryer to dry until the moisture content < 1% to prevent the rehydration of anhydrous gypsum.

[0062] 2. Grinding and classification: Use a Raymond mill or a jet mill to grind to 80 - 200 mesh and package by particle size.

[0063] Step 6: Final product inspection.

[0064] The specific operation of this step is as follows:

[0065] Phase composition analysis: In the four-phase analysis, it is detected that type II anhydrous gypsum in the finished product is converted from CaSO4·2H2O in the raw materials, and the conversion rate is ≥97%.

[0066] In summary, in the process of this application, by perforating the mixed raw materials before the autoclaving step, holes are formed in the mixed raw materials, and its surface area is enlarged in a limited space. Therefore, when performing the subsequent autoclaving treatment, not only can the amount of contact between the mixed raw materials and steam per unit time be increased, but also when multiple holes are set, the mixed raw materials can be heated evenly, improving the reaction rate and conversion rate. At the same time, relying on the existence of the holes before the autoclaving treatment of the mixed raw materials, the subsequent production process can be simplified (no need to add water for granulation and no return material), reducing equipment investment and energy consumption, shortening the batching time and increasing production capacity.

[0067] Example 2:

[0068] Based on the perforating operation in the above production process, we propose a phosphorus gypsum perforating and inserting tooling equipment to more efficiently and conveniently achieve the perforating treatment of the mixed raw materials.

[0069] As Figures 1-8 shown, a phosphorus gypsum perforating and inserting tooling equipment includes a frame 2. A perforating component 1 is movably arranged on the frame 2 along the vertical direction. The perforating component 1 can be set to several groups. For example, in the attached drawings of this application Figure 1 there are three groups as shown. The three groups of perforating components 1 are arranged on the frame 2 along the same straight line direction, and the three groups of perforating components 1 work independently and do not interfere with each other. Below the perforating component 1 is the perforating station. When in use, a walking track can be set at the perforating station, and several feeding trolleys a can be arranged on the walking track. The length of the feeding trolley a can be adapted to the overall length formed by the three perforating components 1. Therefore, when the feeding trolley a loaded with mixed raw materials is at the perforating station, that is Figure 3 the state shown, the perforating component 1 can be driven to move downward to perforate the mixed raw materials.

[0070] As Figure 1As shown in the figure, the drilling assembly 1 includes a transmission box 102 and several drill rods 101 rotatably installed at the bottom of the transmission box 102. The drill rods 101 are made of corrosion-resistant materials. The transmission box 102 is slidably installed on the frame 2 in the vertical direction. A first driving source 103 (preferably a motor) is provided at the top of the transmission box 102. The execution end of the first driving source 103 is connected to the drill rod 101 through a transmission gear assembly inside the transmission box 102, so as to realize that the drill rod 101 can rotate around its own axis. When multiple drill rods 101 are provided, the multiple drill rods 101 are arranged in parallel. A second driving source 9 (preferably a hydraulic cylinder) for driving the drilling assembly 1 to move up and down is provided on the frame 2. The execution end of the second driving source 9 is connected to the transmission box 102. During the process of driving the transmission box 102 and the drill rod 101 to move downward by the second driving source 9, the first driving source 103 can drive the drill rod 101 to rotate itself, so as to realize uniform and gentle hole forming treatment of the mixed raw materials. If the form of non-rotating drill rod 101 is adopted to form holes by hard inserting the drill rod, the resistance of inserting the drill rod will be too large due to too many holes, which will cause damage to the feeding trolley a and the walking track, etc., and the holes formed by hard inserting the drill rod are easy to collapse.

[0071] As Figures 4-8 shown, during the process of the above-mentioned transmission box 102 driving the drill rod 101 to move up and down, if the second driving source 9 fails, the transmission box 102 at a certain height position will suddenly drop out of control, resulting in an accident. Therefore, in order to control and protect the transmission box 102 in an out-of-control state and ensure the operation safety, the present application sets a locking mechanism for ratchet-type locking of the transmission box 102 during the rising process. Therefore, when the second driving source 9 fails, the locking mechanism can limit and protect the transmission box 102 in this state to prevent it from suddenly dropping.

[0072] As Figures 5-6 and Figure 8 shown, specifically: the locking mechanism includes a limit strip 3 provided on the frame 2 and a swing arm 4 rotatably arranged outside the transmission box 102. The limit strip 3 is arranged in the vertical direction, and a plurality of jacks 301 are equidistantly opened along the length direction of the limit strip 3. The swing arm 4 is arranged opposite to the limit strip 3, that is, during the process of the swing arm 4 moving up and down with the transmission box 102, the swing arm 4 can be arranged opposite to any one of the jacks 301 on the limit strip 3. As Figure 8 shown, the swing arm 4 has a pin part 401 close to the limit strip 3 and a counterweight part 402 far from the limit strip 3. A stop rod 5 is arranged outside the transmission box 102 within the moving range of the counterweight part 402, and the stop rod 5 is in contact with the counterweight part 402 to limit the pin part 401 to keep facing the limit strip 3. Figure 5The state shown can be represented as follows: under the action of the counterweight 402 and the stop rod 5, the latch portion 401 remains inserted into the insertion hole 301. When the transmission case 102 drives the swing arm 4 to move upward, the swing arm 4 slides with the top of the latch portion 401 against the top wall of the insertion hole 301, allowing the latch portion 401 to disengage from the insertion hole 301 and come into contact with the non-insertion portion of the limiting strip 3. Therefore, the latch portion 401 has a first working state in which it is inserted into the insertion hole 301 and a second working state in which it comes into contact with the non-insertion portion of the limiting strip 3.

[0073] by Figure 8 From the angle shown, the stopper rod 5 will interfere with the counterweight portion 402 that is rotating counterclockwise, that is, it will block the counterclockwise movement of the swing arm 4; the stopper rod 5 will not interfere with the counterweight portion 402 that is rotating clockwise, that is, it will not block the clockwise movement of the swing arm 4, thus realizing the counterclockwise unidirectional rotation characteristic of the swing arm 4. Figure 8 In the state shown, when the swing arm 4 moves upward along with the transmission box 102, the top of the latch portion 401 can slide in contact with the top wall of the socket 301, causing the latch portion 401 to rotate counterclockwise. Since the swing arm 4 can rotate counterclockwise in one direction, the latch portion 401 of the swing arm 4 will disengage from the socket 301 and move upward. As the swing arm 4 continues to move upward and the counterweight portion 402 acts as a limiter, the latch portion 401 will come into conflict with the non-socket portion of the limit strip 3. That is, during the upward movement, the latch portion 401 switches back and forth between the first working state and the second working state, and will not be obstructed during the upward movement. Figure 5 In the state shown, at this time, if the second driving source 9 suddenly fails, the swing arm 4 will move downward along with the transmission box 102 until the latch portion 401 is in the first working state and the bottom end of the latch portion 401 conflicts with the bottom wall of the socket 301. At this time, the latch portion 401 has a clockwise movement trend, and the counterweight portion 402 will be blocked by the stop rod 5. This state can be Figure 8 To illustrate, the above-mentioned swing arm 4 has a counterclockwise unidirectional rotation characteristic and does not have a clockwise rotation characteristic. Therefore, under the blocking action of the stop rod 5 on the counterweight part 402, the latch part 401 will tightly contact the inner wall of the socket 301, thereby locking the position of the transmission box 102 on the socket 301, effectively preventing the occurrence of accidental falling accidents.

[0074] If the locking relationship between the middle swing arm 4 and the socket 301 needs to be released, the locking mechanism provided in the present application further includes a third driving source (not shown) provided outside the transmission case 102. The execution end of the third driving source can drive the swing arm 4 to rotate so that the latch portion 401 of the swing arm 4 moves out of the socket 301. For example, the third driving source is a cylinder. When the lifting fault of the cylinder is released, Figure 8In the state shown, the cylinder drives the transmission box 102 and the swing arm 4 to move upward for a distance until the latch portion 401 of the swing arm 4 has enough space to rotate counterclockwise. Then, the cylinder can be used to drive the swing arm 4 to rotate counterclockwise until the latch portion 401 moves out of the socket 301, that is, the locking relationship between the swing arm 4 and the socket 301 is released. Subsequently, the cylinder can drive the transmission box 102 and the drill rod 101 to perform a corresponding downward movement. It should be noted that the connection relationship between the execution end of the third driving source and the swing arm 4 in this embodiment is not limited. For example, the execution end can be in a conflicting relationship with the swing arm 4. Initially, the execution end retracts and does not contact the swing arm 4. When working, the execution end extends and conflicts with the swing arm 4 to achieve the rotation of the swing arm 4. Or other conventional working methods are also possible.

[0075] For example Figure 8 As shown, in order to ensure that the latch portion 401 can be smoothly disengaged from the top wall of the socket 301 during the ascending process of the swing arm 4, a guiding slope 403 is provided at the top of the latch portion 401, and the height of the two ends of the guiding slope 403 gradually increases from the end of the swing arm 4 close to the limiting strip 3 to the end away from the limiting strip 3. In order to ensure that the latch portion 401 can be firmly pressed against the bottom wall of the socket 301 during the descending process of the swing arm 4, a pad 6 for supporting the latch portion 401 is fixedly provided at the bottom wall of the socket 301, and the pad 6 is arranged horizontally. The provision of the pad 6 increases the contact area between the pad 6 and the latch portion 401, thereby achieving maximum stable contact between the latch portion 401 and the socket 301.

[0076] For example Figure 1 As shown, in order for the second driving source 9 to smoothly drive the punching assembly 1 to drive the swing arm 4 to perform a lifting action, the present application designs a frame 2 with four evenly distributed support rods 201, and the four ends of the transmission box 102 are slidably mounted on the four support rods 201. The second driving source 9 is arranged in four groups and evenly distributed on the four support rods 201. The execution end of the second driving source 9 is connected to one end of the transmission box 102. The subsequent four groups of second driving sources 9 work together to achieve a smooth lifting and lowering of the transmission box 102. At the same time, in order to have a good locking effect on the punching assembly 1, the present application arranges the limiting strips 3 into four groups and arranges them on the four support rods 201 respectively, and arranges the swing arms 4 into four groups and arranges them at the four ends of the transmission box 102 respectively. Each group of swing arms 4 is adapted to the corresponding limiting strip 3, so that the locking mechanism constitutes a surface locking of the transmission box 102, and the locking effect is better.

[0077] like Figures 1-2 and Figure 7As shown, during the ascending or descending process of the transmission case 102, in order to make the transmission case 102 move stably in the vertical direction during the lifting process, a transfer bracket 7 is fixedly arranged at the end of the transmission case 102. Two groups of guide wheel sets 8 arranged in a right-angled state are fixedly arranged on the transfer bracket 7, and the two groups of guide wheel sets 8 are respectively in rolling connection with the adjacent sides of the support rod 201. The guide wheel set 8 includes a plurality of rollers 801 rotatably arranged on the transfer bracket 7. The plurality of rollers 801 are arranged along the length direction of the support rod 201, and the rollers 801 are in rolling connection with the side part of the support rod 201. Relying on the guide wheel sets 8 arranged in a right-angled state to achieve rolling contact with the support rod 201 for vertical guidance and limit the degrees of freedom of the drilling assembly 1 other than vertical movement. To optimize the overall design of the equipment, based on the design of the transfer bracket 7, the execution end of the second drive source 9 can be connected to the transfer bracket 7.
