Description
Technical Field
[0001] The utility model relates to the technical field of railway construction handheld tools, in particular to a multifunctional handheld tool for railway construction. Background Art
[0002] In railway construction, a wide range of hand tools are required to complete a variety of tasks, from installing and maintaining track to handling related equipment and materials.
[0003] Internal combustion bolt wrenches generally refer to bolt wrenches that can use internal combustion engines (such as gasoline or diesel engines) as a power source. This type of tool is usually used in situations where high torque or a large number of bolt tightening jobs are required, such as in railway construction.
[0004] Internal combustion bolt wrenches usually generate a certain degree of vibration when working. This vibration mainly comes from the vibration and torque output of the internal combustion engine. At present, special shock-absorbing mechanisms, such as rubber sleeves, are designed on the handles or shanks of internal combustion bolt wrenches. The rubber sleeves on the handles have poor shock-absorbing effect and can only have a shock-absorbing effect on the contact surface between the operator's hand and the tool. The overall shock-absorbing performance cannot be improved.
[0005] To this end, we propose a multifunctional handheld tool for railway construction. Utility Model Content
[0006] The utility model mainly solves the above technical problems and provides a multifunctional handheld tool for railway construction.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme, based on a multifunctional handheld tool for railway construction, including an internal combustion bolt wrench body, a moving part and a handheld part;
[0008] The main body of the internal combustion bolt wrench is composed of an engine and a fuselage, a sleeve is movably mounted on the free end of the fuselage through a drive shaft, a shock absorbing assembly for shock absorption is provided on the fuselage, and a movable connecting block is provided on the fuselage;
[0009] The hand-held part is arranged on the shock absorbing assembly, and the hand-held part comprises a secondary handle and a main handle;
[0010] The moving part comprises a walking block, the front and rear sides of the walking block are fixedly mounted with brackets, the brackets are movably mounted with walking wheels, the top surface of the walking block is fixedly mounted with a fixed seat, and a rotating protective sleeve having a structure adapted to the sleeve structure is rotatably mounted on the fixed seat;
[0011] A left-right symmetrical connecting arm is movably mounted on the outer wall surface of the rotating protective sleeve via a rotating shaft, and one end of the connecting arm away from the rotating protective sleeve is rotatably connected to the movable connecting block.
[0012] Preferably, the shock absorbing assembly comprises a shock absorbing box with a hollow structure, the internal fixed sleeve of the shock absorbing box is provided with a rubber connecting sleeve, the rubber connecting sleeve is fixedly connected to the fuselage with the shock absorbing box, and buffer particles are arranged in the hollow structure of the shock absorbing box.
[0013] Preferably, the buffer particles may be rubber particles, polymer particles, or rubber-metal composite particles.
[0014] Preferably, the auxiliary handle is fixedly sleeved on the shock absorbing box, and the auxiliary handles are distributed around the shock absorbing box. The main handle is fixedly installed on the auxiliary handle. The internal combustion bolt wrench body will vibrate during work, and when in use, the operator will hold the main handle to control the position of the internal combustion bolt wrench body. The vibration generated by the internal combustion bolt wrench body during work is transmitted to the shock absorbing assembly. Through the mutual cooperation of the rubber connecting sleeve and the buffer particles, the vibration force is greatly reduced, thereby preventing the vibration force from being transmitted to the operator through the main handle.
[0015] Preferably, a threaded sleeve is fixedly sleeved on the movable connection block, a threaded section is provided on the fuselage, and the movable connection block is threadedly connected to the fuselage via the threaded sleeve. Beneficial Effects
[0016] The utility model provides a multifunctional handheld tool for railway construction, which has the following beneficial effects:
[0017] (1) In the multifunctional hand-held tool for railway construction, the main body of the internal combustion bolt wrench will vibrate during operation. When in use, the operator will hold the main handle to control the position of the main body of the internal combustion bolt wrench. The vibration generated by the main body of the internal combustion bolt wrench during operation is transmitted to the shock absorbing component. The mutual cooperation between the rubber connecting sleeve and the buffer particles greatly reduces the vibration force, thereby preventing the vibration force from being transmitted to the operator through the main handle, reducing the fatigue of the operator during construction, and preventing the operator from having local arm vibrations during construction, which may cause tremors, soreness, joint pain and other problems, thereby improving the comfort of using the hand-held tool.
[0018] (2) In the multifunctional hand-held tool for railway construction, when the walking block is located directly below the sleeve, people fix the movable connecting block with their hands, and then rotate the body to move the sleeve downward until the sleeve is set in the rotating protective sleeve. At this time, the walking block is relatively fixed at the lower end of the body. At this time, the main handle is pushed, so that the main handle drives the main body of the internal combustion bolt wrench to move freely under the assistance of the two sets of walking wheels, thereby facilitating the transfer and movement of the device, achieving the effect of protecting the sleeve and facilitating transfer.
[0019] (3) The multifunctional hand-held tool for railway construction, when installing or removing bolts along the railway track, controls the sleeve to separate upward from the rotating protective sleeve, then pulls the travel block outward, so that the travel block and the travel wheels are distributed on the railway track, pushes the main handle, so that the main handle pushes the travel block to move along the railway track under the action of the travel wheels. Since the rotating protective sleeve is rotatably installed on the fixed seat, the main handle is pushed and pulled to swing left and right, so that the main handle drives the rotating protective sleeve to rotate back and forth through the connecting arm, thereby facilitating the control of the position of the internal combustion bolt wrench body, so that the internal combustion bolt wrench body can be freely distributed on both sides of the railway track. By adjusting the position of the internal combustion bolt wrench body, it is convenient to tighten, install or remove the bolts on both sides of the railway track, thereby improving the flexibility of the hand-held tool.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Embodiment 1: Based on a multifunctional handheld tool for railway construction, such as Figure 1-Figure 4 As shown, it includes an internal combustion bolt wrench body, a moving part and a hand-held part;
[0030] The main body of the internal combustion bolt wrench is composed of an engine 1 and a fuselage 2. A heat dissipation port 8 is provided on one side of the engine 1. A fuel tank 6 is fixedly installed on the side of the engine 1 away from the heat dissipation port 8. A fuel tank cap 7 is provided on the fuel tank 6. The fuel tank cap 7 is opened to facilitate oil filling into the fuel tank 6. A counterweight block 9 is also sleeved on the fuselage 2. A sleeve 10 is movably installed on the free end of the fuselage 2 through a driving shaft.
[0031] Furthermore, a shock absorbing assembly 3 for shock absorption is provided on the fuselage 2, and the handheld part is provided on the shock absorbing assembly 3. The shock absorbing assembly 3 includes a shock absorbing box 300 with a hollow structure, and a rubber connecting sleeve 301 is fixedly sleeved inside the shock absorbing box 300. The rubber connecting sleeve 301 is fixedly sleeved on the fuselage 2 with the shock absorbing box 300. Buffer particles 302 are provided in the hollow structure of the shock absorbing box 300. The buffer particles 302 can be rubber particles, polymer particles, or rubber-metal composite particles.
[0032] The hand-held part includes an auxiliary handle 4 and a main handle 5. The auxiliary handle 4 is fixedly sleeved on the shock absorbing box 300. The auxiliary handles 4 are distributed around the shock absorbing box 300. The main handle 5 is fixedly installed on the auxiliary handle 4. The internal combustion bolt wrench body will vibrate during work. When in use, the operator will hold the main handle 5 to control the position of the internal combustion bolt wrench body. The vibration generated by the internal combustion bolt wrench body during work is transmitted to the shock absorbing assembly 3. Through the mutual cooperation of the rubber connecting sleeve 301 and the buffer particles 302, the vibration force is greatly reduced, and the vibration force is prevented from being transmitted to the operator through the main handle 5, thereby reducing the fatigue of the operator during construction and avoiding local vibration of the operator's arm during construction, which may cause tremors, soreness, joint pain and other problems.
[0033] Embodiment 2, on the basis of embodiment 1, the moving part comprises a walking block 13, a bracket 14 is fixedly installed on both the front and rear sides of the walking block 13, a walking wheel 15 is movably installed in the bracket 14, a fixing seat 16 is fixedly installed on the top surface of the walking block 13, and a rotating protective cover 17 whose structure is adapted to the structure of the sleeve 10 is rotatably installed on the fixing seat 16;
[0034] Furthermore, a left-right symmetrical connecting arm 12 is movably mounted on the outer wall of the rotating protective sleeve 17 through a rotating shaft, and one end of the connecting arm 12 away from the rotating protective sleeve 17 is rotatably connected to the movable connecting block 11, a threaded sleeve is fixedly sleeved on the movable connecting block 11, a threaded section is provided on the fuselage 2, and the movable connecting block 11 is threadedly connected to the fuselage 2 through the threaded sleeve;
[0035] When the walking block 13 is located directly below the sleeve 10, people fix the movable connecting block 11 with their hands, and then rotate the body 2 to move the body 2 with the sleeve 10 downward until the sleeve 10 is sleeved in the rotating protective sleeve 17. At this time, the walking block 13 is relatively fixedly located at the lower end of the body 2, and the main handle 5 is pushed, so that the main handle 5 drives the main body of the internal combustion bolt wrench to move freely under the assistance of the two sets of walking wheels 15, thereby facilitating the transfer and movement of the device;
[0036] When installing or removing bolts along the railway track, the sleeve 10 is controlled to separate upward from the rotating protective sleeve 17, and the walking block 13 is pulled outward at this time, so that the walking block 13 and the walking wheel 15 are distributed on the railway track, and the main handle 5 is pushed, so that the main handle 5 pushes the walking block 13 to move along the railway track under the action of the walking wheel 15. Since the rotating protective sleeve 17 is rotatably installed on the fixing seat 16, the main handle 5 is pushed and pulled at this time to swing left and right, so that the main handle 5 drives the rotating protective sleeve 17 to rotate back and forth through the connecting arm 12, thereby facilitating the control of the position of the internal combustion bolt wrench body, so that the internal combustion bolt wrench body can be freely distributed on both sides of the railway track. By adjusting the position of the internal combustion bolt wrench body, it is convenient to tighten, install or remove the bolts on both sides of the railway track.
[0037] The traveling wheel 15 moves along the railway track, so that people do not need to lift the internal combustion bolt wrench body when changing the construction point, which greatly reduces people's labor intensity.
[0038] The working principle of the utility model is as follows:
[0039] The main body of the internal combustion bolt wrench will vibrate during operation, and when in use, the operator will hold the main handle 5 to control the position of the main body of the internal combustion bolt wrench. The vibration generated by the operation of the main body of the internal combustion bolt wrench is transmitted to the shock absorbing component 3. Through the mutual cooperation of the rubber connecting sleeve 301 and the buffer particles 302, the vibration force is greatly reduced, avoiding the vibration force from being transmitted to the operator through the main handle 5, reducing the fatigue of the operator during construction, and avoiding local vibration of the operator's arm during construction, which may cause tremors, soreness, joint pain and other problems.
[0040] When the walking block 13 is located directly below the sleeve 10, people fix the movable connecting block 11 with their hands, and then rotate the body 2 to move the body 2 with the sleeve 10 downward until the sleeve 10 is sleeved in the rotating protective sleeve 17. At this time, the walking block 13 is relatively fixedly located at the lower end of the body 2, and the main handle 5 is pushed, so that the main handle 5 drives the main body of the internal combustion bolt wrench to move freely under the assistance of the two sets of walking wheels 15, thereby facilitating the transfer and movement of the device;
[0041] When installing or removing bolts along the railway track, the sleeve 10 is controlled to separate upward from the rotating protective sleeve 17, and the walking block 13 is pulled outward at this time, so that the walking block 13 and the walking wheel 15 are distributed on the railway track, and the main handle 5 is pushed, so that the main handle 5 pushes the walking block 13 to move along the railway track under the action of the walking wheel 15. Since the rotating protective sleeve 17 is rotatably installed on the fixing seat 16, the main handle 5 is pushed and pulled at this time to swing left and right, so that the main handle 5 drives the rotating protective sleeve 17 to rotate back and forth through the connecting arm 12, thereby facilitating the control of the position of the internal combustion bolt wrench body, so that the internal combustion bolt wrench body can be freely distributed on both sides of the railway track. By adjusting the position of the internal combustion bolt wrench body, it is convenient to tighten, install or remove the bolts on both sides of the railway track.
[0042] The traveling wheel 15 moves along the railway track, so that people do not need to lift the internal combustion bolt wrench body when changing the construction point, which greatly reduces people's labor intensity.
