Description

Technical Field

[0001] This invention relates to the field of unit-type hoisting technology, specifically a unit-type hoisting assembly artillery vehicle. Background Technology

[0002] With the rapid development of science and technology and the construction industry in my country, high-rise and super high-rise buildings are becoming increasingly common. The use of unitized curtain walls in wall decoration is also becoming more widespread. Almost all high-rise, super high-rise, large stadiums, and office buildings use unitized curtain wall decoration. The installation safety and efficiency of unitized curtain walls have thus become key concerns for building management. The installation of unitized curtain walls, especially glass curtain wall units, is challenging due to the weight of the units themselves, making centralized stacking and unloading on unloading platforms difficult and posing a high risk factor.

[0003] During the unit installation process, the high-rise building is divided into several groups at equal intervals, with the lowest floor of each group serving as the material placement layer and the highest floor as the gun vehicle placement layer. First, a crane or gantry is used to stack several units on the material placement layer, and then the gun vehicle is placed on the placement layer.

[0004] Before using the dartboard, special lubricating oil needs to be evenly applied to the hoisting rope to reduce friction between the rope and the pulley on the boom. After a period of use, the lubricating oil deteriorates and needs to be cleaned off the rope to avoid affecting the normal operation of the dartboard. In existing technology, the dartboard needs to be disassembled one by one, and the hoisting rope needs to be removed and placed on a cleaning device for cleaning. During the cleaning process, the dartboard cannot be used, delaying the construction progress. Summary of the Invention

[0005] The purpose of this invention is to provide a modular, hoisted assembly artillery vehicle to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a unit-type hoisting and assembly artillery vehicle, comprising: The main body of the artillery vehicle includes a front boom, pulleys, and a winch; The maintenance mechanism is installed on the front boom. The hoisting rope on the winch extends out of the winch, passes through the maintenance mechanism and the pulley at the front end of the front boom, and finally hangs down to the ground for hoisting the unit body. When the winch 103 winds up the hoisting rope 104, the maintenance mechanism cleans the oil stains on the hoisting rope 104 by squeezing and scraping; when the winch 103 unwinds the hoisting rope 104, the maintenance mechanism evenly applies new lubricating oil to the hoisting rope 104.

[0007] Furthermore, the maintenance mechanism includes a support frame, an annular frame, and extrusion components. The support frame is symmetrically provided with two through holes. There are two annular frames, each rotatably disposed within the corresponding two through holes. Several extrusion components are fixed between the annular frames on both sides. The several extrusion components are assembled together along the circumference to form an extrusion ring. The suspension rope passes through the extrusion ring along the thickness direction of the extrusion component. The annular frame includes a through hole, and the inner diameter of the compression ring is smaller than the diameter of the through hole.

[0008] Furthermore, the extrusion component includes an extrusion block and a force-bearing block. The force-bearing block is located on the outer ring surface of the extrusion block. Several limiting grooves are provided on both side walls of the extrusion block, which are radially distributed along the extrusion ring. Several limiting blocks are provided on the annular frame, which are adapted to the limiting grooves, so that the limiting blocks are inserted into the limiting grooves. The extrusion block has several limiting holes 1, and the annular frame 3 has several limiting holes 2. When the extrusion block is installed in place, the corresponding limiting holes 1 and limiting holes 2 are aligned, and positioning pins are inserted to fix the relative positions of the extrusion block and the annular frame.

[0009] Furthermore, the support frame 2 is also provided with a power component, which is used to drive the ring frame 3 to rotate; Along the outer ring surface direction of the extrusion block 401, the distance from the edge line of the force-bearing block 402 to the outer ring surface of the extrusion block 401 gradually decreases; A resisting block 12 is provided on the support frame 2 at the position corresponding to the force-bearing block 402. The resisting block 12 cooperates with the force-bearing block 402 and squeezes the force-bearing block 402 toward the inside of the compression ring when the force-bearing block 402 rotates.

[0010] Furthermore, the power component one includes a motor and a spur gear two. The motor is located on a support frame, and the output shaft of the motor is provided with a spur gear one. The spur gear two is located on an annular frame near the winch, and the spur gear two meshes with the spur gear one.

[0011] Furthermore, the surface on the extruder used for scraping off oil stains is surface a, the support frame is provided with a detachable collection box on the side away from the winch, and the annular frame is provided with a primary scraping component above the support frame for scraping off the oil stains accumulated on surface a. The collection box includes a side line b parallel to surface a. The collection box is provided with a slide that moves along the side line b. The slide is provided with a secondary scraper. The primary scraper is located between the extrusion block and the secondary scraper. When the primary scraper moves into the working range of the secondary scraper, it scrapes off the oil stains on the primary scraper.

[0012] Furthermore, the primary scraping component includes a support frame one, which is located on the inner ring surface of the annular frame. The support frame one has a scraper plate one at its end, and a drainage groove is formed on the scraper plate one. The drainage groove is provided with a scraper plate two and a telescopic component. The telescopic component controls the scraper plate two to slide along the thickness direction of the annular frame. The scraper plate two is inclinedly arranged in the drainage groove. The scraper plate two has an inclined surface c, and the inclined surface c forms an angle with the annular frame. The vertex of the angle is located at the end near the center of the annular frame. The secondary scraping component includes a second bracket, which is fixed on a slide. The end of the second bracket is provided with a third scraper, which is located within the range of the opening on the collection box. The third scraper is located on a slope d near the primary scraping component, and the slope d is parallel to the slope c.

[0013] Furthermore, the bracket 701 is equipped with a power component 2, which controls the rotation of the scraper 702.

[0014] Furthermore, an oil outlet pipe is provided on the side of the support frame near surface a, with the oil outlet end of the oil outlet pipe pointing towards the suspension rope, for dripping lubricating oil onto the suspension rope, and an oiling surface e is provided on the side of the scraper away from the drain trough.

[0015] Furthermore, the gun body also includes a base frame, a counterweight bracket, and a tie rope. The front boom, winch, and counterweight bracket are sequentially installed on the base frame using bolts. One end of the front boom with a pulley is connected to the housing of the winch via the tie rope, which also includes an adjustable turnbuckle.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention includes a gun carriage body and a maintenance mechanism located on the front boom of the gun carriage body. The hoisting rope extends from the winch, passes through the maintenance mechanism and a pulley at the front end of the front boom, and finally hangs down to the ground. When the winch winds up the hoisting rope, oil stains on the rope are cleaned by squeezing and scraping; when the winch unwinds the hoisting rope, new lubricating oil is evenly applied to the rope. This allows for cleaning and changing the lubricating oil on the hoisting rope without stopping work, improving the overall efficiency of construction operations. It can also be used with hoisting ropes of different thicknesses, enhancing the practicality of the device. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-8 .

[0020] This invention provides a modular, hoisted, assembled artillery vehicle, comprising: The main body of the artillery vehicle includes a front boom 101, pulleys 102 and winch 103; The maintenance mechanism is installed on the front boom 101. The hoisting rope 104 on the winch 103 extends out of the winch 103, passes through the maintenance mechanism and the pulley 102 at the front end of the front boom 101, and finally hangs down to the ground for hoisting the unit body. When the winch 103 winds up the hoisting rope 104, the maintenance mechanism cleans the oil stains on the hoisting rope 104 by squeezing and scraping; when the winch 103 unwinds the hoisting rope 104, the maintenance mechanism evenly applies new lubricating oil to the hoisting rope 104.

[0021] In a set of floors, the main body of the mortar is transported to the placement floor for assembly. The main body of the mortar includes a base frame 105, a front boom 101, a winch 103, and a counterweight bracket 106. The front boom 101, the winch 103, and the counterweight bracket 106 are bolted to be installed on the base frame 105 in sequence, which facilitates the transportation of the mortar and on-site assembly, making the construction convenient, safe and reliable. The hoisting rope 104 on the winch 103 extends out of the winch 103, passes through the through hole 301 of the ring frame 3 and the pulley 102 at the front end of the front boom 101, and finally hangs down to the ground. The end of the hoisting rope 104 is connected to a hook for hoisting the unit body of the material layer.

[0022] To enhance the load-bearing capacity of the front boom system, one end of the front boom 101 with a pulley 102 is connected to the housing of the winch 103 via a tie rope 107. The tie rope 107 also includes an adjustable turnbuckle 108.

[0023] During construction, the hoisting rope 104 was cleaned as needed on site. After cleaning, the extrusion part 4 was removed and stored separately. The cleaning steps are as follows: Step S1: Assemble several extrusion parts 4 around the support frame 2 to obtain an extrusion ring. The support frame 2 is symmetrically provided with through holes 201, and an annular frame 3 is rotatably provided in each of the two through holes 201. The two side walls of the annular frame 3 are provided with four limiting grooves 403 along their radial direction. The annular frame 3 is provided with several limiting blocks 302 that are adapted to the limiting grooves 403. Take the first extrusion block 401 and place it into the support frame 2. Align the limiting grooves 403 on both sides of the extrusion block 401 with the limiting blocks 302 on both sides of the insertion ring frame 3. Push the extrusion block 401 into the support frame 2 along the length of the limiting block 302 until the limiting hole 1 on the limiting block 302 aligns with the limiting hole 2 on the support frame 2. At this point, the extruder is installed in place. Take a positioning pin 404 and insert it into the corresponding limiting hole 1 and limiting hole 2 to complete the assembly of the first extrusion block 401. Similarly, assemble the second extrusion block 401.

[0024] Because the inner diameter of the compression ring is slightly smaller than the diameter of the suspension rope 104 in its natural state, the last two compression blocks 401 require considerable manual force to install into place after contacting the suspension rope 104. To make the installation of the last two compression blocks 401 easier, a force-bearing block 402 is provided on the outer ring surface of the compression block 401. Along the outer ring surface of the compression block 401, the distance from the edge line of the force-bearing block 402 to the outer ring surface of the compression block 401 gradually decreases, and the width of the force-bearing block 402 gradually decreases from the wide end to the narrow end. When the narrow end of the force-bearing block 402 enters the range of the support frame 2, the power component drives the ring frame 3 to rotate (rotation direction as shown in 4). The ring frame 3 passes through the limiting groove 40. The insertion of the limit block 302 causes the extrusion block 4 to rotate synchronously. The rotation causes the narrow end of the force-bearing block 402 to pass through the abutment block 12 first. Since part of the force-bearing block 402 is still outside the range of the support frame 2, the outer edge of the force-bearing block 402 will eventually fit with the abutment block 12. Under the blocking action of the abutment block 12, the rotating force-bearing block 402 continues to enter the support frame 2 along the length direction of the limit groove 403 until the head end of the force-bearing block 402 contacts the abutment block 12. The extrusion block 4 is then installed in place. A positioning pin 404 is taken and inserted into the corresponding limit hole one and limit hole two to complete the assembly of the third extrusion block 401. Similarly, the fourth extrusion block 401 is assembled.

[0025] Step S2, scraping off old oil stains: The winding machine drives the hanging rope 104 to wind up. As the hanging rope 104 is pulled from the extrusion ring, the oil stains on the hanging rope 104 are squeezed and scraped off, and the oil stains accumulate on the outer wall of the extrusion ring. Step S3, collecting oil stains: The surface on the extruder 4 used to scrape off oil stains is surface a, that is, the side of the extruder 401 away from the winch 103. A primary scraping component is provided on the annular frame 3 above the support frame 2. A collection box 6 is provided on the side of the support frame 2 near surface a. The annular frame 3 drives the primary scraping component on its outer wall to rotate synchronously. The primary scraping component includes a bracket 701, which is located on the inner annular surface of the annular frame 3. A scraper 702 is provided at the end of the bracket 701. A drain trough 703 is provided on 702. A second scraper 704 is provided in the drain trough 703, which slides along the thickness direction of the annular frame 3. The second scraper 704 is inclined in the drain trough 703 and has an inclined surface c. The inclined surface c forms an angle with the annular frame 3. The vertex of the angle is located at one end close to the center of the annular frame 3. The first scraping component scrapes the oil stains into the drain trough 703 between the second scraper 704 and the first scraper 702. The contaminated lubricating oil has a certain viscosity. The collection box 6 is detachably mounted on the support frame 2. The collection box 6 includes a side line b parallel to surface a. The collection box 6 is provided with a slide 61 that moves along the side line b. The slide 61 is provided with a secondary scraper. The primary scraper is located between the compression ring and the secondary scraper. The secondary scraper includes a second bracket 801, which is fixed on the slide 61. The end of the second bracket 801 is provided with a third scraper 802. The third scraper 802 is located within the opening of the collection box 6. The third scraper 802 has an inclined surface d on one side near the primary scraper. The inclined surface d is parallel to the inclined surface c. When the primary scraper rotates and moves into the working range of the secondary scraper, the telescopic component inside scraper 1 702 extends, driving scraper 2 704 forward along the side wall of scraper 1 702 until the inclined surface c completely exceeds scraper 1 702. The top of the collection box 6 is equipped with a linear power device (not shown in the diagram), such as a cylinder. The drive end of the cylinder drives the slide 61 and the secondary scraper to move forward. The inclined surface d of scraper 3 802 and the inclined surface of scraper 2 704 separate after approaching and adhering, thereby cleaning the oil stains collected on scraper 2 704 and preventing the oil stains from accumulating in the support frame 2 and re-contaminating the suspension rope 104. As the primary scraper continues to rotate away from the secondary scraper, the secondary scraper moves in the opposite direction and resets, thereby scraping off the oil stains on the suspension rope 104.

[0026] If the lifting rope 104 is replaced with one of different thicknesses, then the corresponding extrusion block 401 can be inserted. The inner diameter of the extrusion block 401 is smaller than the diameter of the through hole 301 of the annular frame 3. The difference between the extruded parts 4 of different specifications is the different inner diameters of the extrusion block 401. The support 701 has a power component 2 (not shown in the figure) inside, which controls the rotation of the scraper 702. Specifically: During cleaning, when scraper 702 rotates in the forward direction (rotation direction as follows) Figure 6 As shown, the distance between scraper 702 and suspension rope 104 can be increased; when scraper 702 rotates in the opposite direction, the distance between scraper 702 and suspension rope 104 can be reduced; so that scraper 702 can be adapted to suspension rope 104 of different thicknesses. During oiling, the scraper 702 has an oiling surface e on the side away from the drain trough 703. When the scraper 702 rotates in the reverse direction (e.g. Figure 6 (in the opposite direction shown), the distance between the oiled surface e and the suspension rope 104 can be increased. When the scraper 702 rotates in the forward direction (rotation direction as shown), Figure 6 As shown, the distance between the oiling surface e and the suspension rope 104 can be reduced, and the oiling surface e can be made to adhere to the outer wall of the suspension rope by rotation. This allows for oiling operations with suspension ropes 104 of different thicknesses, improving the practicality of the device.

[0027] After cleaning, the winding machine releases the hoisting rope 104. An oil outlet pipe 9 is located on the side of the support frame 2 near surface a. The oil inlet of the oil outlet pipe 9 is connected to an external oil supply device, and the oil outlet points to the hoisting rope 104. During the descent of the hoisting rope 104, oil is evenly dripped onto it. Simultaneously, the power component drives the annular frame 3 and the primary scraping component to rotate, causing the oil-coated surface e to rotate around the hoisting rope 104, evenly spreading the lubricating oil onto it. The end of the hoisting rope 104 hardly contacts the pulley 102, so lubricant maintenance does not affect the use of the end of the hoisting rope 104. The lubricating oil on the hoisting rope 104 can be cleaned and replaced without stopping work, improving the overall efficiency of the construction operation.

[0028] The power component includes a motor 501 and a second spur gear 503. The motor 501 is located on the support frame 2. The output shaft of the motor 501 is equipped with a first spur gear 502. The second spur gear 503 is located on an annular frame 3 near the winch 103, and the second spur gear 503 meshes with the first spur gear 502. The output shaft of the motor 501 drives the first spur gear 502 to rotate, and after the first spur gear 502 meshes with the second spur gear 503, it drives the annular frame 3 to rotate.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0030] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0032] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
