Description

Technical Field

[0001] The utility model relates to the field of rail welding, in particular to a rail joint grinding and inspection tool. Background Art

[0002] With the increasingly severe epidemic situation abroad and the continuous development of the globalized economy, port trade activities have become more frequent, which has put higher and higher requirements on the performance of port machinery, prompting the continuous progress of the port machinery manufacturing industry. As an important component to ensure the safe and smooth operation of the main trolley of the port machinery, the quality of the trolley track is crucial.

[0003] Since the length of the trolley track is relatively long, it is generally processed in sections and then welded together to complete the production of the trolley track. In this process, after the sections are welded into a whole, the welds will be polished to make the surface of the guide rail smooth, avoiding the protruding welds or residual welding slag that affect the subsequent stable movement of the trolley. At present, after polishing, it is usually judged by manual naked eye observation whether the track surface is smooth, which has high labor intensity, and long-term observation will also have a certain impact on people's vision. In addition, it is easy to make judgment errors and the accuracy is not high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rail joint grinding and inspection tool which is convenient for carrying out smoothness inspection on the welding joint of the rail.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a track joint grinding inspection tool, the innovation of which is: including

[0006] An inspection bracket, wherein the upper end surface of the inspection bracket is a horizontal plane;

[0007] A moving assembly installed in the inspection bracket, the moving assembly includes a pair of rollers distributed in parallel, the two sides of the rollers are connected to the inspection bracket through the cooperation of bearings, and an annular groove for accommodating the track to be embedded is also opened on the circumferential surface of the rollers, the two rollers are respectively a large roller and a small roller of different sizes, and the upper end surface of the inspection bracket is a first plane and a second plane that cooperate with the large roller and the small roller, and the height of the first plane is higher than the height of the second plane;

[0008] A pair of support rods are connected to both sides of the inspection bracket.

[0009] Furthermore, the connection between the support rod and the inspection bracket is as follows: a pair of vertically arranged connecting sleeves are respectively connected to both sides of the inspection bracket, and a through hole is opened on the connecting sleeve for accommodating the support rod to pass through and move up and down. The support rod and the connecting sleeve are fixed by the cooperation of bolts and nuts. Several first through holes distributed in sequence from top to bottom and accommodating the passage of bolts are opened on the support rod, and several second through holes distributed in sequence from top to bottom and accommodating the passage of bolts are also opened on the connecting sleeve.

[0010] Furthermore, a supporting circular plate is connected to the bottom end surface of the support rod.

[0011] Furthermore, the inspection bracket is also connected to a push handle located at the second plane.

[0012] Furthermore, a pair of lifting ears are installed on the upper end surfaces of the inspection bracket located on the first plane and the second plane.

[0013] The advantages of the utility model are as follows: the inspection tool in the utility model utilizes the mutual cooperation of the detection bracket and the moving assembly to simulate the state of the trolley running on the track, and judges whether the track is polished and smooth by observing the walking state of the detection bracket, so the inspection is more convenient, and the design of the support rod plays a supporting role for the entire tool when it stays on the track and does not move, so as to avoid tipping over.

[0014] The connection between the support rod and the inspection bracket adopts the cooperation of the connecting sleeve, the first through hole, the second through hole, bolts, nuts and other components, thereby realizing a movable connection between the support rod and the inspection bracket, so that the height of the support rod relative to the inspection bracket can be adjusted according to the height of different tracks to achieve support for the inspection bracket.

[0015] The design of the supporting circular plate on the bottom surface of the support rod can more stably support the inspection bracket when the support rod is used to support the inspection bracket, thereby avoiding the shaking of the inspection bracket.

[0016] The design of the push handle is to facilitate personnel to push the entire inspection tool to move on the track. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the rail joint grinding and inspection tooling of the utility model.

[0019] Figure 2 for Figure 1 AA section view. DETAILED DESCRIPTION

[0020] The following embodiments may enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0021] like Figure 1 , Figure 2 A rail joint grinding inspection tool is shown, comprising

[0022] An inspection bracket 1, wherein the upper end surface of the inspection bracket 1 is a horizontal plane.

[0023] A moving component is installed in the inspection bracket 1, and the moving component includes a pair of rollers distributed in parallel. The two sides of the rollers are connected to the inspection bracket 1 through the cooperation of bearings. An annular groove 5 for accommodating the embedding of the track 2 is also opened on the circumferential surface of the roller. The two rollers are a large roller 3 and a small roller 4 of different sizes, and the height of the bottom end surface of the large roller 3 is flush with the height of the bottom end surface of the small roller 4. At the same time, the upper end surface of the inspection bracket 1 is a first plane 11 and a second plane 12 that cooperate with the large roller and the small roller, and the height of the first plane 11 is higher than the height of the second plane 12.

[0024] A push handle 14 is also connected to the inspection bracket 1 at the second plane 12, and the push handle 14 is arranged obliquely and extends out of the inspection bracket 1. The design of the push handle 14 is to facilitate personnel to push the entire inspection tooling to walk on the track 2.

[0025] A pair of lifting ears 13 are also installed on the upper end surfaces of the inspection bracket 1 located on the first plane 11 and the second plane 12. The design of the lifting ears 13 is to facilitate the subsequent lifting of the entire inspection tooling onto the track 2 before or after the inspection, or to lift it out of the track 2 without manual handling.

[0026] A pair of vertically arranged support rods 6 are connected to both sides of the inspection bracket 1. The support rods 6 are cylindrical rods. The connection between the support rods 6 and the inspection bracket 1 is as follows: a pair of vertically arranged connecting sleeves 7 are connected to both sides of the inspection bracket 1. The connecting sleeves 7 are cylindrical, and one side of the connecting sleeves 7 is welded and fixed to the side wall of the inspection bracket 1. A through hole is opened on the connecting sleeve 7 to allow the support rods 6 to pass through and move up and down. The support rods 6 and the connecting sleeves 7 are fixed by the cooperation of bolts and nuts. There are several first through holes 61 distributed from top to bottom for bolts to pass through, and several second through holes 71 distributed from top to bottom for bolts to pass through are also opened on the connecting sleeve 7. During installation, the first through hole 61 on the support rod 6 is aligned with the second through hole 71 on the connecting sleeve 7, and then bolts are passed through the second through hole 71 and the first through hole 61 in sequence, and then nuts are used to lock them, thereby achieving the fixation between the support rod 6 and the connecting sleeve 7, and also achieving the relative fixation between the support rod 6 and the inspection bracket 1. For the connection between the support rod 6 and the inspection bracket 1, the connecting sleeve 7, the first through hole 61, the second through hole 71, and the bolts, nuts and other components are used to achieve the movable connection between the support rod 6 and the inspection bracket 1, so that the height of the support rod 6 relative to the inspection bracket 1 can be adjusted according to the height of different tracks 2 later, so as to achieve the support of the inspection bracket 1.

[0027] A supporting circular plate 62 is also connected to the bottom end surface of the support rod 6. The design of the supporting circular plate 62 on the bottom surface of the support rod 6 can more stably support the test bracket 1 when the support rod 6 is used to support the test bracket 1, thereby preventing the test bracket 1 from shaking.

[0028] When inspecting whether the surface of the track 2 is smooth, first use a crane to hoist the entire inspection tool on the track 2 to be inspected, and fit the annular grooves 5 on the large roller 3 and the small roller 4 with the track 2. At this time, the bottom surface of the support rod 6 is not in contact with the ground, that is, the support rod 6 is suspended. Then, the push handle 14 is manually pushed to simulate the state of the trolley running on the track 2, and the walking state of the inspection bracket 1 is observed to judge whether the track 2 is polished and smooth, which is more convenient than directly observing the polished area with the naked eye. When the inspection is paused, the bolts can be removed from the first through hole 61 and the second through hole 71, and then the support rod 6 is pulled to slide in the connecting sleeve 7 until the bottom surface of the support rod 6 contacts the ground, and then the bolts are passed through the first through hole 61 and the second through hole 71 to achieve relative fixation between the support rod 6 and the inspection bracket 1. At this time, the entire inspection tool is temporarily parked on the track 2 to facilitate personnel to perform other operations.
