Description

Technical Field

[0001] This utility model relates to the technical field of bridge maintenance, specifically a tool for cleaning the joints of railway bridge beams. Background Technology

[0002] Railway bridges are structures built to cross rivers, lakes, straits, valleys, or other obstacles, and to facilitate grade separation between railway lines and roads. Railway bridge engineering is a branch of railway engineering, encompassing a range of technologies related to the construction and maintenance of railway bridges. During construction, due to the long distances of some bridges, short-distance bridge deck splicing is often used. To prevent cracking caused by thermal expansion and contraction due to temperature changes, expansion joints are typically cut at designated intervals to buffer these changes. However, over time, these expansion joints may become filled with stones or hard granular materials, hindering the buffering effect of thermal expansion and contraction under significant temperature fluctuations, leading to damage. Therefore, regular cleaning of the bridge beam joints is necessary.

[0003] However, existing tools for cleaning bridge beam joints are usually shovels or similar tools that require workers to bend over for extended periods to remove hard impurities from the beam joints. This method and the tools used for extended periods can put a significant strain on the workers' bodies, potentially causing joint injuries and other health problems. Furthermore, this method is inefficient. Therefore, this design proposes a new tool for cleaning railway bridge beam joints. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for cleaning the joints of railway bridge beams, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model proposes a tool for cleaning the joints of railway bridge beams, including a mounting shell and a support mechanism mounted on the top of the mounting shell;

[0005] The support mechanism includes multiple support shafts inserted at both ends of the bottom of the mounting housing. Two support plates are fixedly connected between each support shaft. A support frame is connected between the two support plates. Mounting blocks are installed at both ends of the support frame. Electric push rods are installed at the bottom of the two mounting blocks. Multiple limiting holes are opened on both sides of the bottom of the mounting housing. The outer wall of each support shaft is inserted into the inner wall of each limiting hole. A spring is sleeved on the outer wall of each support shaft. The two ends of each spring are fixedly connected to the top of the two support plates and the bottom of the mounting housing, respectively. A mounting groove is opened in the middle of the inner wall of the mounting housing. A seam cleaning blade is rotatably connected to the inner wall of the mounting groove. Rollers are installed on both sides of the bottom of the two support plates.

[0006] In one example, two connecting brackets are installed at the middle position of the lower edge of one side of the mounting housing, and guide wheels are rotatably connected between the two connecting brackets.

[0007] In one example, a motor is mounted on one side of the top of the mounting housing, and one end of the seam cleaning blade passes through the outer wall of one side of the mounting housing and is fixedly connected to the output end of the motor.

[0008] In one example, a handle is fixedly connected between the two ends of the top of the support frame, and a limit sleeve is installed on both sides of the top edge of the mounting housing.

[0009] In one example, the outer walls of the two output ends of the electric actuators are respectively inserted into the inner walls of the two limiting sleeves, and a protective shell is installed on the top side of the mounting housing at the outer edge of the motor.

[0010] In one example, a control switch is installed on one side of the grip, and the electric actuator and motor are electrically connected to an external power source via the control switch.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a support mechanism, when cleaning the beam joints, the workers only need to push the support frame so that the support plate moves along the direction of the beam joint through the rollers at the bottom, and start the electric push rod to press down the support shaft to lower the housing, so that the cleaning blade disc descends into the beam joint and drives the rotation to perform roller cleaning. Later, the electric push rod retracts and the housing rises under the action of the spring, so that the cleaning blade disc is away from the ground, and the device can be pushed away. In the whole process, the workers do not need to bend over to operate tools to remove impurities in the beam joints, reducing physical strain, and improving the cleaning efficiency of bridge beam joints.

Detailed Implementation

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

[0019] Please see Figure 1-5 This utility model provides a technical solution: a tool for cleaning the gaps in railway bridge beams, including a mounting shell 1 and a support mechanism 2 installed on the top of the mounting shell 1;

[0020] The support mechanism 2 includes multiple support shafts 201 inserted at both ends of the bottom of the mounting housing 1. Two support plates 202 are fixedly connected between each support shaft 201. A support frame 203 is connected between the two support plates 202. Mounting blocks 204 are installed at both ends of the support frame 203. Electric push rods 205 are installed at the bottom of each of the two mounting blocks 204. Multiple limiting holes 206 are provided on both sides of the bottom of the mounting housing 1, and the outer wall of each support shaft 201 is inserted into and connected to the inner wall of each limiting hole 206. Springs 207 are fitted on the outer walls, and the two ends of each spring 207 are fixedly connected to the top of the two support plates 202 and the bottom of the mounting shell 1, respectively. A mounting groove 208 is opened in the middle of the inner wall of the mounting shell 1. A cleaning blade 209 is rotatably connected to the inner wall of the mounting groove 208. Rollers 210 are installed on both sides of the bottom of the two support plates 202. The cleaning blade 209 is made of a metal material with high hardness. During the cleaning process, the blade will cut and brush out some hard blocky materials, thus improving the cleaning effect.

[0021] During use, the operator can hold the handle 3 and push the support frame 203 to move the support plate 202 along the beam seam via the rollers 210 at its bottom. During the movement, the cleaning blade 209 in the mounting slot 208 faces the beam seam and is driven to rotate. Then, the electric push rod 205 at the bottom of the mounting block 204 is activated to extend and retract synchronously and press against the mounting housing 1. This causes the mounting housing 1 to compress the spring 207 and slide down on the support shaft 201, thereby causing the cleaning blade 209 to descend and continuously rotate the roller brush in the inner wall of the beam seam, cutting and sweeping out the hard parts. After cleaning, the electric push rod 205 is retracted, raising the height of the mounting housing 1. The cleaning blade 209 is then removed from the ground, allowing the entire device to be moved away. During this process, the operator does not need to manually operate the cleaning tool, bend over or squat near the beam seam for manual cleaning. They only need to stand and walk to operate the entire cleaning tool along the beam seam, reducing the operator's workload, reducing physical strain, and improving the cleaning efficiency of the beam seam.

[0022] Furthermore, two connecting brackets 211 are installed at the middle position of the lower edge of the housing 1. A guide wheel 212 is rotatably connected between the two connecting brackets 211, and the guide wheel 212 is flush with the cleaning blade disc 209. During the cleaning process, when the cleaning blade disc 209 enters the beam joint, the guide wheel 212 also descends and rolls in the beam joint. Therefore, when the operator moves the cleaning tool, he only needs to pay attention to whether the guide wheel 212 deviates from the beam joint and thus control the direction of the tool so that the cleaning blade disc 209 is always on the inner wall of the beam joint for brush cleaning.

[0023] Furthermore, a motor 213 is installed on one side of the top of the mounting housing 1, and one end of the cleaning blade 209 passes through the outer wall of one side of the mounting housing 1 and is fixedly connected to the output end of the motor 213. When operating the tool, the operator can control the cleaning blade 209 to rotate and clean the hard impurities in the beam joint by starting and stopping the motor 213 on the handle 3.

[0024] Furthermore, a handle 3 is fixedly connected between the two ends of the top of the support frame 203, and a limiting sleeve 4 is installed on both sides of the top edge of the mounting housing 1. When the electric push rod 205 extends and retracts, its output end extends and retracts in the limiting sleeve 4, which can ensure the stability of the mounting housing 1 being compressed, and at the same time also protect the output end of the electric push rod 205.

[0025] Furthermore, the outer walls of the output ends of the two electric push rods 205 are respectively inserted and connected to the inner walls of the two limiting sleeves 4. A protective shell 5 is installed on one side of the top of the mounting shell 1 at the outer edge of the motor 213, and a protective shell 5 is also installed on one side of the mounting shell 1 at the outer edge of the motor 213, which serves to protect the motor 213.
