Support adjusting beam jack puller

Abstract

This utility model belongs to the field of hammer pulling, especially the hammer pulling of a jack for adjusting the beam of a support frame. The existing method uses a small hammer mounted on the pin of the support frame beam for pulling. However, due to rust inside the pin, it requires continuous pulling with the small hammer, which is difficult to remove. This not only sometimes results in the small hammer becoming loose and detaching, posing a safety hazard, but is also time-consuming and labor-intensive. The proposed solution includes a base, with a sliding rod fixedly connected to the center of the base. A hammer is slidably mounted on the sliding rod, and the hammer has a sliding hole adapted to the sliding rod. A connecting plate is detachably connected to the top of the sliding rod. This utility model uses a hammer instead of the original small hammer, making pin pulling easier, reducing damage to the beam and labor intensity. At the same time, the moving mechanism can mitigate the impact force to a certain extent, protecting the device and the operator's safety.

Description

Technical Field

[0001] This utility model relates to the field of jacking hammer technology, and in particular to a jacking hammer for adjusting the support beam. Background Technology

[0002] As the demand for supports in underground work increases, the pins on the base plate of the hydraulic support need to be pulled out during maintenance and disassembly. Since the pins rust after long-term use, a small hammer was originally used to pull out the pins by installing it on the pin of the support adjustment beam. However, due to the rust inside the pin of the adjustment beam, it was difficult to pull it out even with continuous pulling by the small hammer. This not only caused the small hammer to sometimes come loose during use, which could easily lead to injury and safety hazards, but it was also time-consuming and laborious, affecting the efficiency of maintenance and installation of supports.

[0003] Therefore, we propose a support beam adjusting jack puller to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support adjustment beam jack pull hammer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The support beam adjusting jack hammer includes a base, a sliding rod fixedly connected to the center of the base, a weight slidably mounted on the sliding rod, a sliding hole adapted to the sliding rod on the weight, a connecting plate detachably connected to the top of the sliding rod, a connecting column fixedly connected to the center of the connecting plate, a connecting seat fixedly connected to the connecting column, a U-shaped lug on the connecting seat, and a connecting hole on the U-shaped lug;

[0007] It also includes a moving mechanism mounted on the base for easy movement and to mitigate impact.

[0008] The weighting part is set on the hammer and is used to increase the weight of the hammer.

[0009] In one possible design, the moving mechanism includes a moving frame and moving wheels. The moving frame is fixedly connected to the other side of the base, and there are two moving wheels, which are rotatably connected to the moving frame via bearings.

[0010] In one possible design, the weighting part includes a weight block, a plurality of second bolts, and second bolt holes on the hammer that are adapted to the second bolts. Both the weight block and the hammer have sliding holes adapted to the sliding rod.

[0011] In one possible design, stabilizing plates are fixedly connected to both sides of the connecting column on the connecting plate. The two stabilizing plates are inclined and fixedly connected to both sides of the connecting seat, forming a triangular shape with the connecting seat.

[0012] In one possible design, mounting plates are fixedly connected to both sides of the weight, and fixed plates are detachably connected to the mounting plates. A connecting ring is provided on the fixed plate, and mounting feet are fixedly connected to the fixed plate. The mounting feet have through holes, and the mounting plates have first bolt holes. The mounting feet are connected to the first bolt holes through the first bolts.

[0013] In one possible design, a connecting bolt is fixedly connected to the slide rod, and a connecting screw hole is provided at the center of the connecting plate, with the connecting bolt threaded into the connecting screw hole.

[0014] In this application, during specific use, the third part is first fixedly connected to the connecting hole on the connecting seat through the third part. The third part can be a steel wire. The steel wire passes through the connecting hole and is tied. Then, the steel wire is bound to the through hole radially driven into the end face of the pin. This can fix the pin. Then, the rope can be tied to the connecting ring. When pulling the pin, the worker holds the rope and makes the hammer slide on the slide bar. The hammer is used to impact the base by inertia. Because a moving wheel is set, the moving wheel can move relative to the base when the hammer impacts the base, which can reduce the impact force.

[0015] When it is necessary to increase the weight of the counterweight, the connecting plate can be rotated to disengage the connecting screw hole from the connecting bolt. Then, the weight block is passed through the slide rod and fits against the counterweight. It is then connected to the second bolt hole through the second bolt, thus fixing the weight block to the counterweight. This increases the weight of the counterweight, making it easier to pull out the pin. At the same time, the slide rod and the connecting plate can be disassembled, allowing the counterweight to be disassembled for easy removal and maintenance.

[0016] In this utility model, a counterweight is used instead of the original small counterweight, making it easier to pull out the pin and reducing the damage to the beam and labor intensity during the pin pulling process.

[0017] In this invention, by setting up a moving mechanism, the impact force can be mitigated to a certain extent, protecting the safety of the device and the operator.

[0018] In this invention, by adding a weighting part, the weight of the hammer can be increased as needed, making it suitable for different requirements. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figure 1-4 The puller hammer, used in the field of puller hammers, includes a base 1, which serves as the supporting foundation for the entire device. A sliding rod 2 is fixedly connected to the center of the base 1. The sliding rod 2 is made of cold-drawn round steel, possessing high wear resistance, high hardness, and good weldability. This ensures that the surface of the sliding rail will not be damaged or rusted when the hammer 3 is moved on it during subsequent welding and hammer removal. The hammer 3 is slidably mounted on the sliding rod 2, allowing it to slide freely. A connecting plate 4 is detachably connected to the top of the sliding rod 2. A connecting column 5 is fixedly connected to the center of the connecting plate 4, and a connecting seat 6 is fixedly connected to the connecting column 5. The connecting seat 6 has a U-shaped lug with a connecting hole 7 for connecting with other equipment or tools.

[0027] In order for the base 1 to move and to mitigate the impact force of the hammer 3, a moving mechanism is provided, which includes a moving frame 10 and moving wheels 11.

[0028] The movable frame 10 is fixedly connected to the other side of the base 1, and there are two movable wheels 11, which are rotatably connected to the movable frame 10 through bearings. The movable mechanism allows the hammer to be moved easily within the work area. At the same time, the design of the movable wheels 11 can also mitigate the impact force to a certain extent, protecting the safety of the device and the operator.

[0029] The counterweight 3 is the main working component of this hammer. Its weight can be adjusted by a weighting mechanism, which includes a weight block 18, multiple second bolts 19, and second bolt holes 20 on the counterweight 3 that are compatible with the second bolts 19. By placing the weight block 18 on the counterweight 3 and fixing it to the counterweight 3 using the second bolts 19, the weight of the counterweight 3 is increased. Both the weight block 18 and the counterweight 3 have sliding holes that are compatible with the sliding rod 2. This design allows the hammer to flexibly adjust the weight of the counterweight 3 according to different working requirements, thereby improving work efficiency.

[0030] This application is used in the field of support and beam adjustment, but it can also be used in other fields.

[0031] Example 2

[0032] refer to Figure 1-4 Improvements based on Example 1: Support adjustment beam jack pull hammer:

[0033] To enhance the stability between the connecting plate 4 and the connecting seat 6, stabilizing plates 8 are fixedly connected to both sides of the connecting column 5 on the connecting plate 4. The two stabilizing plates 8 are set at an angle and fixedly connected to both sides of the connecting seat 6 to form a triangular structure, which improves the stability of the connection.

[0034] Mounting plates 9 are fixedly connected to both sides of the hammer 3. A fixing plate 12 is detachably connected to the mounting plate 9, and a connecting ring 13 passes through the fixing plate 12 for connecting other tools or equipment. Mounting feet are also fixedly connected to the fixing plate 12, and the mounting feet have through holes. The mounting plate 9 has a first bolt hole 15. The fixing plate 12 is connected to the first bolt hole 15 via a first bolt 14, achieving a detachable connection between the fixing plate 12 and the mounting plate 9. By connecting a rope to the connecting ring 13, the hammer 3 can be operated more easily.

[0035] A connecting bolt 16 is fixedly connected to the slide rod 2, and a connecting screw hole 17 is provided at the center of the connecting plate 4. The slide rod 2 and the connecting plate 4 are detachably connected by the threaded connection between the connecting bolt 16 and the connecting screw hole 17. This design allows the connecting plate 4 to be easily installed or removed as needed, which facilitates the addition of weights and makes it easy to remove the counterweight 3 for maintenance.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
