Description

Technical Field

[0001] This utility model relates to the field of anchor drilling rig technology, and in particular to an anti-impact structure for a hydraulic outrigger type anchor drilling rig. Background Technology

[0002] Anchor drilling rigs, also known as anchoring drilling rigs, have a wide range of applications. They play a crucial role in various geological disaster prevention projects, such as landslide control and rock mass anchoring, particularly in high slope rock mass anchoring. In urban construction, this equipment is equally effective, suitable for deep foundation pit support, anti-buoyancy anchoring, and drilling in foundation grouting reinforcement projects. In blasting projects, it can precisely drill blasting holes; it is also indispensable for high-pressure jet grouting pile construction and tunnel pipe roof support drilling. Notably, with only slight adjustments to its power head, it can flexibly achieve omnidirectional construction, greatly improving operational convenience and applicability.

[0003] Patent publication number "CN215632802U" discloses "A Leg-Type Anchor Drill Rig with Shock Absorption Function," comprising a connecting strip and a conical seat. A stud is fixedly connected to the outer surface of the conical seat, and the outer surface of the stud is threadedly connected to the support leg of the drill rig. An air intake assembly is provided on the outside of the conical seat, and a movable groove is formed on the outer surface of the connecting strip. This relates to the field of anchor drill rig technology. This leg-type anchor drill rig with shock absorption function, by setting up a shock absorption mechanism, when the drill rig is impacted by a reaction force, an external pneumatic device supplies gas into the air passage and air distribution pipe, which enters the air bladder through the connecting pipe. The increased pressure inside the air bladder causes it to bulge, thereby pushing the connecting strip to move in the opposite direction to reduce pressure. Simultaneously, the elasticity of the air bladder and the internal pressure counteract the reaction force of the drill rig to achieve the purpose of shock absorption. This combination of structures solves the problem that existing anchor drill rigs, lacking shock absorption devices, are easily damaged by reaction force impacts.

[0004] The device in the aforementioned patent moves the slider via the connecting plate and bolts through the movement of the drilling rig. This causes the slider to compress the telescopic rod and spring, using the spring force to enhance the shock absorption effect. If the recoil force is too large, the outer side of the slider will slide in contact with the inner side of the groove over a large area, generating a large friction force. If the device is under such a large friction force for a long time, the slider is very likely to experience excessive wear and other problems, affecting the normal operation and service life of the device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides an anti-impact structure for a hydraulic outrigger type anchor bolt drilling rig.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a counter-impact structure for a hydraulic outrigger type anchor bolt drilling rig, comprising a base plate, wherein a first counter-impact mechanism is provided inside the base plate, and a second counter-impact mechanism is provided above the base plate;

[0009] The first anti-impact mechanism includes a sliding groove and a sliding block. The outer side of the sliding block is located inside the sliding groove. Small pulleys and large pulleys are rotatably connected to both sides and the bottom surface of the sliding block, respectively. The outer sides of the small pulleys and the outer sides of the large pulleys are slidably connected to the inner side of the sliding groove. A first telescopic rod and a first spring are fixedly installed on the inner wall of one end of the sliding groove, respectively. The outer side of the first telescopic rod is located inside the first spring, and one end of the first telescopic rod and the first spring are fixedly installed on the surface of one end of the sliding block.

[0010] By adopting the above technical solution, small pulleys and large pulleys are rotatably connected to the sides and bottom of the sliding block, respectively. The outer sides of the small pulleys and large pulleys slide against the inner side of the sliding groove, thereby effectively reducing friction. The rotational characteristics of the pulleys further improve the sliding effect of the sliding block, ensuring smoother operation of the device. This solves the problem that if the recoil force is too large, the outer side of the slider will slide against the inner side of the sliding groove over a large area, generating large friction. If the device is under such large friction for a long time, the slider may experience excessive wear, affecting the normal operation and service life of the device.

[0011] As a preferred embodiment of the anti-impact structure of the hydraulic outrigger type anchor bolt drilling machine of this utility model, the sliding groove of the first anti-impact mechanism is opened on the surface of the base plate and penetrates through the interior, a support rod is fixedly installed on the top surface of the sliding block, and an adjustable anchor bolt drilling machine body is fixedly installed on the top end of the support rod.

[0012] By adopting the above technical solution, the base plate provides a stable opening position for the sliding groove that is opened on the surface and penetrates through the interior. The support rod installed on the surface of the sliding block can build an installation platform for the adjustable anchor drilling rig body installed at the top, which facilitates the smooth operation of the anchor drilling rig body and ensures efficient operation.

[0013] As a preferred embodiment of the anti-impact structure of the hydraulic outrigger type anchor bolt drilling rig described in this utility model, the second anti-impact mechanism includes a support plate and a column. The bottom end of the column is fixedly installed on one side surface of the support plate. A second telescopic rod and a second spring are fixedly installed on the bottom wall of the column. The outer side of the second telescopic rod is located inside the second spring. A limit cylinder is slidably connected to the inner wall of the top end of the column. One end of the second telescopic rod and the second spring are fixedly installed on the top wall of the limit cylinder.

[0014] By adopting the above technical solution, when the limiting cylinder encounters a counter-impact, the second telescopic rod and the second spring installed on the top wall work together. Under the action of the counter-impact force, the second telescopic rod first retracts to provide initial buffering. At the same time, the second spring is compressed and absorbs the counter-impact energy through its own elastic deformation. The two work together to achieve a highly efficient buffering effect, effectively preventing excessive counter-impact from being transmitted to other parts of the device, preventing structural damage or loosening of components due to excessive impact, ensuring stable operation of the device and maintaining normal working condition.

[0015] As a preferred embodiment of the anti-impact structure of the hydraulic outrigger type anchor bolt drilling machine described in this utility model, the bottom surface of the support plate of the second anti-impact mechanism is fixedly installed on the surface of the base plate.

[0016] By adopting the above technical solution, the base plate can effectively provide a stable installation position for the support plate installed on the surface.

[0017] As a preferred embodiment of the anti-impact structure of the hydraulic outrigger type anchor bolt drilling machine of this utility model, a reinforcing rod is fixedly installed on the other side surface of the support plate of the second anti-impact mechanism, and the bottom end of the reinforcing rod is fixedly installed on the surface of the base plate.

[0018] By adopting the above technical solution, the support plate achieves stable support by means of a reinforcing rod installed on its other side surface. The bottom end of the reinforcing rod is firmly fixed to the surface of the base plate. This reinforcement method greatly improves the stability of the support plate, ensuring that it can always maintain a stable state when bearing various loads, and providing reliable support for the connected equipment or structure.

[0019] As a preferred embodiment of the anti-impact structure of the hydraulic outrigger type anchor bolt drilling machine of this utility model, the limiting cylinder of the second anti-impact mechanism is fixedly installed on one side of the support rod, and the bottom surface of the base plate is fixedly installed with support feet.

[0020] By adopting the above technical solution, the support feet installed on the bottom surface of the base plate can effectively support the gravity from the device.

[0021] (III) Beneficial Effects

[0022] This utility model provides a counter-impact structure for a hydraulic outrigger type anchor bolt drilling rig. It has the following beneficial effects:

[0023] 1. By adding a first counter-impact mechanism, small and large pulleys are rotatably connected to the sides and bottom of the sliding block, respectively. The outer sides of the small and large pulleys slide against the inner side of the sliding groove, thereby effectively reducing friction. The rotational characteristics of the pulleys further improve the sliding effect of the sliding block, ensuring smoother operation of the device. This solves the problem that if the counter-impact force is too large, the outer side of the slider will slide against the inner side of the sliding groove over a large area, generating significant friction. If the device is under such significant friction for a long time, the slider may experience excessive wear, affecting the normal operation and service life of the device.

[0024] 2. By adding a second anti-impact mechanism, when the limiting cylinder encounters an anti-impact, the second telescopic rod and the second spring installed on the top wall work together. Under the action of the anti-impact force, the second telescopic rod first retracts to provide initial buffering. At the same time, the second spring is compressed and absorbs the anti-impact energy through its own elastic deformation. The two work together to achieve an efficient buffering effect, effectively preventing excessive anti-impact from being transmitted to other parts of the device, preventing structural damage or loosening of parts due to excessive impact, ensuring stable operation of the device and maintaining normal working condition.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a counter-impact structure for a hydraulic outrigger type anchor bolt drilling machine, including a base plate 1, a first counter-impact mechanism 2 inside the base plate 1, and a second counter-impact mechanism 5 above the base plate 1.

[0034] The first anti-impact mechanism 2 includes a sliding groove 21 and a sliding block 22. The outer side of the sliding block 22 is located inside the sliding groove 21. Small pulleys 23 and large pulleys 24 are rotatably connected to the two sides and the bottom surface of the sliding block 22, respectively. The outer sides of the small pulleys 23 and the large pulleys 24 are slidably connected to the inner side of the sliding groove 21, respectively. A first telescopic rod 25 and a first spring 26 are fixedly installed on the inner wall of one end of the sliding groove 21, respectively. The outer side of the first telescopic rod 25 is located inside the first spring 26, and one end of the first telescopic rod 25 and the first spring 26 are fixedly installed on one end surface of the sliding block 22.

[0035] Specifically, the sliding groove 21 of the first counter-impact mechanism 2 is opened on the surface of the base plate 1 and extends through the interior. A support rod 3 is fixedly installed on the top surface of the sliding block 22, and an adjustable anchor drill body 4 is fixedly installed on the top of the support rod 3.

[0036] Furthermore, when the sliding block 22 encounters a counter-impact, the first anti-impact mechanism 2 works in concert with the first telescopic rod 25 and the first spring 26 installed on the top wall. Under the action of the counter-impact force, the first telescopic rod 25 first contracts to provide stroke for initial buffering. At the same time, the first spring 26 is compressed and absorbs the counter-impact energy through its own elastic deformation. The two work together to achieve a buffering and resisting effect. Then, the sliding block 22 is rotatably connected to the bottom surface by the small pulley 23 and the large pulley 24 on both sides. The outer sides of the small pulley 23 and the large pulley 24 slide with the inner side of the sliding groove 21, thereby effectively reducing the friction. The rotation characteristics of the pulleys further improve the sliding effect of the sliding block 22, ensuring smoother operation of the device. The sliding groove 21 is opened on the surface of the bottom plate 1 and extends through the interior.

[0037] The support rod 3 installed on the surface of the sliding block 22 can build an installation platform for the adjustable anchor drilling rig body 4 installed at the top, which facilitates the smooth operation of the anchor drilling rig body 4 and ensures efficient operation.

[0038] Example 2

[0039] Reference Figures 1 to 4This is the first embodiment of the present invention. This embodiment is based on the previous embodiment. The second counter-impact mechanism 5 includes a support plate 51 and a column cylinder 52. The bottom end of the column cylinder 52 is fixedly installed on one side surface of the support plate 51. The bottom wall of the column cylinder 52 is fixedly installed with a second telescopic rod 53 and a second spring 54. The outer side of the second telescopic rod 53 is located inside the second spring 54. The inner wall of the top end of the column cylinder 52 is slidably connected to a limit cylinder 55. One end of the second telescopic rod 53 and the second spring 54 are fixedly installed on the top wall of the limit cylinder 55.

[0040] Specifically, the bottom surface of the support plate 51 of the second counter-impact mechanism 5 is fixedly installed on the surface of the base plate 1, and a reinforcing rod 6 is fixedly installed on the other side surface of the support plate 51 of the second counter-impact mechanism 5. The bottom end of the reinforcing rod 6 is fixedly installed on the surface of the base plate 1. The limiting cylinders 55 of the second counter-impact mechanism 5 are fixedly installed on one side of the support rod 3, and the bottom surface of the base plate 1 is fixedly installed with support feet 7.

[0041] Furthermore, when the limiting cylinder 55 encounters a counter-impact, the second anti-impact mechanism 5 works in concert with the second telescopic rod 53 and the second spring 54, which are respectively installed on the top wall. Under the action of the counter-impact force, the second telescopic rod 53 first contracts to provide stroke for initial buffering. At the same time, the second spring 54 is compressed and absorbs the counter-impact energy by its own elastic deformation. The two work together to achieve a highly efficient buffering and resistance effect. The other ends of the second telescopic rod 53 and the second spring 54 are respectively installed on the bottom wall of the column cylinder 52. The bottom end of the column cylinder 52 is respectively installed on one side surface of the support plate 51, and the limiting cylinder 55 is respectively installed on one side of the support rod 3.

[0042] The support plate 51 is stably supported by the reinforcing rod 6 installed on its other side surface. The bottom end of the reinforcing rod 6 is firmly fixed to the surface of the base plate 1. This reinforcement method greatly improves the stability of the support plate 51, ensuring that it can always remain stable when bearing various loads, and providing reliable support for the connected equipment or structure. The support feet 7 installed on the bottom surface of the base plate 1 can effectively support the gravity from the device.

[0043] Working principle: When the sliding block 22 encounters a counter-impact, the first anti-impact mechanism 2 works in concert with the first telescopic rod 25 and the first spring 26 installed on the top wall. Under the action of the counter-impact force, the first telescopic rod 25 first contracts to provide stroke for initial buffering. At the same time, the first spring 26 is compressed and absorbs the counter-impact energy by its own elastic deformation. The two work together to achieve a buffering and resisting effect. Then, the sliding block 22 is rotatably connected to the small pulley 23 and the large pulley 24 on both sides and the bottom surface, respectively. The outer sides of the small pulley 23 and the large pulley 24 slide with the inner side of the sliding groove 21, thereby effectively reducing the friction. The rotation characteristics of the pulleys further improve the sliding effect of the sliding block 22, ensuring smoother operation of the device. The sliding groove 21 is opened on the surface of the bottom plate 1 and extends through the interior.

[0044] The support rod 3 installed on the surface of the sliding block 22 can build an installation platform for the adjustable anchor drilling rig body 4 installed at the top, which facilitates the smooth operation of the anchor drilling rig body 4 and ensures efficient operation.

[0045] When the limiting cylinder 55 encounters a counter-impact, the second anti-impact mechanism 5 works in concert with the second telescopic rod 53 and the second spring 54 installed on the top wall. Under the action of the counter-impact force, the second telescopic rod 53 first contracts to provide stroke for initial buffering. At the same time, the second spring 54 is compressed and absorbs the counter-impact energy by its own elastic deformation. The two work together to achieve an efficient buffering and resistance effect. The other ends of the second telescopic rod 53 and the second spring 54 are respectively installed on the bottom wall of the column cylinder 52. The bottom end of the column cylinder 52 is respectively installed on one side surface of the support plate 51, and the limiting cylinder 55 is respectively installed on one side of the support rod 3.

[0046] The support plate 51 is stably supported by the reinforcing rod 6 installed on its other side surface. The bottom end of the reinforcing rod 6 is firmly fixed to the surface of the base plate 1. This reinforcement method greatly improves the stability of the support plate 51, ensuring that it can always remain stable when bearing various loads, and providing reliable support for the connected equipment or structure. The support feet 7 installed on the bottom surface of the base plate 1 can effectively support the gravity from the device.
