Description

Technical Field

[0001] The present invention relates to a high-safety integrated drilling and anchoring trolley, and in particular to a high-safety integrated drilling and anchoring trolley applied in the technical field related to drilling and anchoring trolleys. Background Art

[0002] Bolting refers to a reinforcement method used in surface engineering projects such as slopes and deep rock foundation pits, as well as in underground chambers such as tunnels and stopes. Bolts are made of metal, wood, polymer, or other materials and driven into pre-drilled holes in the surface rock mass or the rock mass surrounding the chamber. Bolting utilizes the special structure of the head and body, and a tail support plate (optional), or relies on bonding to combine the surrounding rock with the stable rock mass, changing the mechanical state of the surrounding rock itself. This creates a holistic and stable rock belt around the roadway. The combined action of the bolts and the surrounding rock creates a suspension effect, a composite beam effect, and a reinforcement effect, achieving the support purpose.

[0003] During the construction of the drilling and anchoring trolley, the realization of various actions such as drilling and anchoring mostly requires the cooperation of multiple cylinders in the hydraulic system. For example, a new type of double-bend rock drilling trolley disclosed in Chinese patent CN117738585B is also designed with multiple hydraulic cylinders. Therefore, the cylinders play an important role in the construction of the trolley.

[0004] In a single-arm hydraulic tunneling drilling rig disclosed in Chinese patent CN118775380A, although improvements have been made to the hydraulic cylinder, the improvements are mainly aimed at the temperature of the hydraulic oil. However, after long-term use, the cylinder will produce some granular impurities in the hydraulic oil due to internal wear and tiny impurities brought in from the outside, which not only affects the lubrication effect of the hydraulic oil, but also reduces the service life of the hydraulic oil. Therefore, after a certain period of time, the hydraulic oil needs to be replaced. The drilling and anchoring rig generally requires long-term continuous construction, resulting in a high replacement frequency, which affects normal construction. In addition, when the hydraulic oil becomes abnormal, the hydraulic system's control over the operating arm becomes weak, and the target construction point is prone to deviation, posing certain safety hazards. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that as the use time increases, granular impurities are likely to appear in the hydraulic oil, affecting its use.

A plurality of connecting rods are clamped between the oil filter cylinder and the fixed section, and a one-way valve is installed at the mouth of the oil inlet pipe and the oil outlet pipe near the fixed section.

[0008] In the above-mentioned high-safety drilling and anchoring integrated trolley, through the setting of the external circulation unit, when the oil cylinder is extended and retracted, the hydraulic oil will be filtered outside the cylinder, thereby effectively collecting and intercepting the backflow of some impurities into the oil chamber. Compared with the existing technology, it can effectively extend the service life of the hydraulic oil, reduce the replacement frequency, and effectively avoid the impact of the presence of granular impurities in the hydraulic oil on construction.

[0009] As a further improvement of the present application, the pitch and elevation angles of the telescopic arm are 30° and 60° respectively, and the horizontal swing amplitude of the telescopic arm is ±45°.

[0010] As a further improvement of the present application, the oil filter cylinder includes a cylinder body connected to the oil inlet pipe and the oil outlet pipe, and multiple net bags fixedly connected to the lower end of the cylinder body.

DETAILED DESCRIPTION

[0035] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0036] The first implementation method:

[0037] Figure 1-3A high-safety drilling and anchoring trolley is shown, comprising a trolley body 1 with a control room. The front end of the trolley body 1 is fixedly connected to two arm connecting seats 21. Two telescopic arms 2 are installed on the two arm connecting seats 21 through a cross hinge shaft. A telescopic oil cylinder is installed between the fixed section and the innermost extension end of the telescopic arm 2 to control the extension and shortening of the telescopic arm 2. A variable amplitude oil cylinder 22 is also installed between the cross hinge shaft and the lower end of the telescopic arm 2. The two ends of the variable amplitude oil cylinder 22 are respectively connected to the arm connecting seat 21 and the telescopic arm 2 for rotation. The front end of a telescopic arm 2 A hanging basket 3 is rotatably connected, and a follower cylinder 31 is installed between the bottom of the hanging basket 3 and the front end of the telescopic arm 2. The extended end of the follower cylinder 31 is rotatably connected to the hanging basket 3. A synchronous cylinder 23 is also installed between the lower end of the telescopic arm 2 with the hanging basket 3 and the corresponding cross hinge shaft. Through the cooperation of the synchronous cylinder 23 and the follower cylinder 31, the hanging basket 3 can be controlled to always be in a horizontal state, which is convenient for workers to stand in it and carry out corresponding construction. A swing frame unit 5 is installed at the front end of the other telescopic arm 2, and a working unit 6 is installed at the end of the swing frame unit 5 away from the telescopic arm 2. Figure 7-8 Through the luffing cylinder 22, the pitch and elevation angles of the telescopic arm 2 are respectively 30° and 60°, and the horizontal swing amplitude is ±45°. Through the setting of the luffing cylinder 22, the telescopic arm 2 can be controlled to adjust the angle in the pitch direction and the horizontal direction, thereby driving the hanging basket 3 or the working unit 6 to change position, thereby adapting to construction in different positions.

[0038] like Figure 5 The swing frame unit 5 includes a swivel seat 52, and one end of the swivel seat 52 facing the telescopic arm 2 and the working unit 6 is fixedly connected to a swivel motor 51. One swivel motor 51 is fixedly connected to the end of the telescopic arm 2, and the other end of the swivel motor 51 is rotatably connected to a swing frame seat 53. The end of the swing frame seat 53 away from the swivel motor 51 is fixedly connected to a swing frame body 54, and the upper end of the swing frame body 54 is fixedly connected to a propulsion cylinder 56, and the outer end of the fixed section of the propulsion cylinder 56 is fixedly connected to two lower limit clamps 55, and the end of the extended section of the propulsion cylinder 56 is fixedly connected to a propulsion beam connecting seat, and the working unit 6 is installed on the propulsion beam connecting seat. When in use, the arrangement of the two swivel motors 51 enables the working unit 6 connected to the swing frame unit 5 to achieve 360° rotation in both the vertical and horizontal directions, thereby making the working range of the drilling and anchoring integrated trolley wider. During construction, the entire vehicle body does not need to be frequently adjusted in position, thereby effectively ensuring construction efficiency.

[0039] like Figure 6The working unit 6 slides in matching with the two lower limit clamps 55, and is fixedly connected to the propulsion cylinder 56. The working unit 6 includes a propulsion beam 63, a rock drill 61 and two clamps 62 installed at the upper end of the propulsion beam 63, and a drill rod 64 installed at the end of the rock drill 61. The drill rod 64 and the two clamps 62 match each other. Under the control of the propulsion cylinder 56, the propulsion beam 63 can be moved forward or backward, and the two clamps 62 can be automatically centered, automatically clamped and released to complete the rod connection work.

[0040] like Figure 9-11 , an external circulation unit is also provided outside the fixed section of the telescopic cylinder, the variable amplitude cylinder 22, the follower cylinder 31 and the thrust cylinder 56. The external circulation unit includes an oil inlet pipe 71 and an oil outlet pipe 72 respectively communicated with the two oil chambers, and an oil filter cylinder 8 threadedly connected between the oil inlet pipe 71 and the oil outlet pipe 72. A plurality of connecting rods 701 are clamped between the oil filter cylinder 8 and the fixed section, so that the entire oil filter cylinder 8 can be disassembled from the oil inlet pipe 71 and the oil outlet pipe 72. A one-way valve is installed at the mouth of the oil inlet pipe 71 and the oil outlet pipe 72 near the fixed section, so that the hydraulic oil in the cylinder can only flow along the direction of the oil inlet pipe 71-oil filter cylinder 8-oil outlet pipe 72, so that the filtering direction of the hydraulic oil in the oil filter cylinder 8 is fixed, and it is not easy for the hydraulic oil to flow back, so that the impurities intercepted in the oil filter cylinder 8 are not easy to flow back into the oil chamber.

[0041] First, the oil chambers in the oil cylinder that are identical to the oil inlet pipe 71 and the oil outlet pipe 72 are respectively recorded as the left oil chamber and the right oil chamber.

[0042] When the cylinder needs to be extended, the hydraulic system controls the hydraulic oil in the oil tank to flow into the left oil chamber along the oil pipe, while the hydraulic oil in the right oil chamber flows back to the oil tank along the oil pipe. During this process, part of the hydraulic oil flows into the oil filter cylinder 8 along the oil inlet pipe 71 under the action of oil pressure, and after being filtered, it flows into the right oil chamber along the oil outlet pipe 72, and then flows back to the oil chamber along the oil pipe, thereby filtering part of the hydraulic oil.

[0043] When the oil cylinder needs to be shortened, the hydraulic system controls the hydraulic oil in the oil tank to flow into the right oil chamber along the oil pipe, while part of the hydraulic oil in the left oil chamber flows back to the oil tank along the oil pipe, and the other part of the hydraulic oil flows into the oil filter cylinder 8 along the oil inlet pipe 71, and after being filtered, flows into the right oil chamber along the oil outlet pipe 72, thus completing the filtration of part of the hydraulic oil.

[0044] In summary, during the extension and retraction process of the cylinder, part of the hydraulic oil can always be filtered. Due to the circulation between the hydraulic oil and the oil tank, the cylinder can filter some impurities in the hydraulic oil during operation. Compared with the existing technology, under the same working time and working environment, the amount of impurities in the hydraulic oil is significantly reduced, thereby achieving the effect of extending the life of the hydraulic oil and reducing the replacement frequency.

[0045] like Figure 12 The oil filter cylinder 8 includes a cylinder body 81 connected to the oil inlet pipe 71 and the oil outlet pipe 72, a plurality of net bags fixedly connected to the lower end of the cylinder body 81, and the net bag includes two expansion blocks 83 fixedly connected to the outer end of the cylinder body 81 and an eccentric flat cylinder 82 sealed and clamped at the lower ends of the two expansion blocks 83. The eccentric flat cylinder 82 and the cylinder body 81 are also sealed at the overlap, so that the eccentric flat cylinder 82 can be disassembled, which is convenient for the subsequent cleaning and replacement of the internal dynamic filter 801. The interiors of the cylinder body 81, the eccentric flat cylinder 82 and the expansion blocks 83 are interconnected, the net bag is connected to the cylinder body 81, and the cylinder body is connected to the eccentric flat cylinder 82. There are multiple dynamic filter screens 801 with interference fit inside 81, and a fixed filter screen 802 is fixedly connected to the inner wall of the cylinder 81. The fixed filter screen 802 is located on the side of the multiple net bags close to the oil outlet pipe 72, and the multiple dynamic filter screens 801 are respectively located on the side of the multiple net bags facing the oil inlet pipe 71. Under the action of oil pressure, the hydraulic oil passing through the oil filter cylinder 8 will generate a thrust toward the oil outlet pipe 72 on the dynamic filter screen 801. When more impurities are intercepted on the dynamic filter screen 801, its permeability becomes worse, and the oil pressure it receives at this time also increases, thereby causing the dynamic filter screen 801 to gradually move toward the oil outlet pipe 72. Figure 13-15 , until it reaches the eccentric flat cylinder 82, due to the expansion of the inner diameter, the dynamic filter 801 loses its binding force and will fall into the eccentric flat cylinder 82 under the action of gravity. At this time, the last dynamic filter 801 with better permeability continues to filter the hydraulic oil as the first filter, realizing continuous filtration of the hydraulic oil without the need for manual replacement of the dynamic filter 801, until multiple dynamic filters 801 fall into the eccentric flat cylinder 82, and then replace them, which can effectively extend the one-time use time of the oil filter cylinder 8 and reduce the workload of the staff for its maintenance and replacement.

[0046] The inner wall of the cylinder 81 is also fixedly connected to a plurality of blocking rings 101 corresponding to the plurality of falling net bags. The edge of the blocking ring 101 is flush with the edge of the falling net bag facing the oil outlet pipe 72. The blocking ring 101 is used to limit the falling dynamic filter 801, making it difficult for it to approach the next dynamic filter 801, thereby effectively ensuring the stable filtration of the hydraulic oil by the next dynamic filter 801.

[0047] like Figure 14 The top of the expansion block 83 is higher than the center line of the dynamic filter 801, and the distance between the inner walls of the two expansion blocks 83 is greater than the inner diameter of the cylinder 81. The inner diameter of the eccentric flat cylinder 82 is consistent with the distance between the two expansion blocks 83. When the dynamic filter 801 reaches the eccentric flat cylinder 82, the interval between the two expansion blocks 83 is larger, so that the dynamic filter 801 loses its support, and then it can fall smoothly into the eccentric flat cylinder 82, making it less likely to cause a large obstruction to the hydraulic oil again, facilitating the smooth external circulation of the hydraulic cylinder. The width of the eccentric flat cylinder 82 is 3-5 times the width of the dynamic filter 801.

[0048] A plurality of limiting rings 102 are selectively fixedly connected to the inner wall of the dynamic filter 801. The plurality of limiting rings 102 are respectively located at the edge of the mouth of the plurality of eccentric flat cylinders 82 facing the oil inlet pipe 71, and the cross-section of the limiting ring 102 is arc-shaped. The blocking ring 101 is used to limit the dynamic filter 801, so that the dynamic filter 801 is not easily pushed and falls into the eccentric flat cylinder 82 under very small pressure. Instead, it is required to generate greater resistance to the hydraulic oil, and the oil pressure on its left side increases, so that it is subjected to a greater driving force, so that it can turn over the blocking ring 101 and fall into the eccentric flat cylinder 82, thereby effectively ensuring the utilization rate of the dynamic filter 801 and reducing the occurrence of it falling under good permeability conditions.

[0049] It is worth noting that, during implementation, the following contents can be selectively set according to actual needs:

[0050] Temperature sensors are installed inside and outside the cylinder 81. Multiple cooling plates are embedded in the cylinder 81. Among the two adjacent cooling plates, one cooling end faces the axis of the cylinder 81, and the other heating end faces the axis of the cylinder 81. The power on and off of the cooling plates are controlled by the control room, and the temperature sensor is connected to the control room signal. When in use, the two temperature sensors can detect the ambient temperature and the temperature of the hydraulic oil, so that the control room can control the power on of the cooling plates in different directions, and then heat or cool the hydraulic oil, so that the hydraulic oil is at a relatively stable temperature during operation, so that the hydraulic oil is not prone to excessive viscosity or insufficient viscosity, thereby effectively ensuring stable construction.

[0051] In summary, through the setting of the external circulation unit, when the oil cylinder is extended and retracted once, the hydraulic oil will circulate outside the cylinder once, thereby achieving the effect of collecting and intercepting some impurities outside the cylinder. Compared with the existing technology, it can effectively extend the service life of the hydraulic oil and reduce the replacement frequency, while effectively avoiding the impact of the presence of granular impurities in the hydraulic oil on construction; in the process of extracorporeal circulation filtration of the hydraulic oil, as the impurities intercepted on the dynamic filter 801 increase and the permeability becomes lower, its resistance to the hydraulic oil increases, and then the thrust of the hydraulic oil it receives will also increase, and then it will gradually and spontaneously fall into the net bag, so that the next dynamic filter 801 with good permeability can continue to intercept impurities.

[0052] The second implementation method:

[0053] This embodiment is based on the first embodiment, and a new net-catching monitoring unit is added, while the rest of the parts remain the same as the first embodiment.

[0054] Figure 12As shown, a in the figure represents a laser sensor, and a net-falling monitoring unit is also provided outside the eccentric flat cylinder 82. The net-falling monitoring unit includes an ash-avoiding cover 92 clamped on the outer end of the cylinder 81 and a wide-angle camera 91 installed at the corner below the ash-avoiding cover 92. The ash-avoiding cover 92 is provided outside a plurality of net-falling pockets, such as Figure 13-15 When no movable filter 801 falls to the eccentric flat cylinder 82, the wide-angle camera 91 can obtain images of changes in multiple eccentric flat cylinders, so that the staff can understand the usage of multiple movable filters 801, making it convenient for the staff to replace and adjust the oil filter cylinder 8 in time.

[0055] In this embodiment, the eccentric flat cylinder 82 is made of a transparent material.

[0056] In conjunction with the setting of the net-fall monitoring unit, the falling conditions of multiple dynamic filters 801 can be monitored, which facilitates the staff to take corresponding measures in time, thereby effectively ensuring the service life of the hydraulic oil and reducing the replacement frequency.

[0057] In addition, it is worth noting that Figure 12-13 A laser sensor can also be set at the outer end of the cylinder 81. The emitting end of the laser sensor faces the cylinder 81 and is located between the fixed filter 802 and the oil outlet pipe 72. The part of the cylinder 81 opposite to the laser sensor is set to be transparent. The laser sensor can detect the number and size of impurity particles in the filtered hydraulic oil, which is convenient for timely judging the quality of the filtered hydraulic oil. If there are still many impurities after filtering, the staff can be reminded to replace the hydraulic oil in time.

[0058] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
