Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge cranes, in particular to a bridge crane track quick-changing device. Background Art
[0002] In the past, crane rails were replaced when they were broken, worn, or when the pressure feed exceeded the standard. Steam cranes were used to enter the factory in batches, or winches were used in small quantities.
[0003] These two methods are as follows: first, the motor crane is obviously affected by site limitations and requires sufficient operating rotation space on the ground. Except for the initial construction of the factory, it is difficult to meet this requirement under normal production conditions; second, the winch device is only suitable for vertical lifting and hoisting, and cannot be moved horizontally and transported on the crane platform. Equipment installation and maintenance urgently require a device that can be moved and transported on the crane rail platform. Utility Model Content
[0004] The main purpose of the utility model is to provide a bridge crane rail quick-change device, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A bridge crane track quick-change device comprises a track, a gantry, and a track trolley. The number of the track, the gantry, and the track trolley is two. The track trolley is respectively mounted on the track. The track trolley comprises side panels. The number of the side panels is two. An intermediate panel is fixed on both sides of the side panels. The bottom of the intermediate panel is fixed with side support rods. The side support rods are respectively seated on the track with matching positions. A wheel body is provided between the side panels. Two support rods are fixed to one end of the bottom of the side panel close to the wheel body. Support cylinders are fixed to the bottom of the wheel body at the position of the support rods. The support rods are respectively penetrated and communicated with support cylinders with matching positions.
[0007] Preferably, the outer diameter of the support rod matches the inner diameter of the support cylinder.
[0008] Preferably, the bottom of the support cylinder is threadedly connected to a limiting screw, and one end of the limiting screw is respectively inserted into the interior of the support cylinder and contacts the bottom of the support rod.
[0009] Preferably, baffles are fixed to both ends of the top of the wheel body.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. The two rail trolleys set on the rails can be used to move the new and old rails, making the rail transportation easy and convenient. After moving to the area to be disassembled and assembled, the new and old rails can be lifted and lowered by the hand hoist on the gantry.
[0012] 2. The track trolley of the present application can be adapted and adjusted according to the width between different tracks, so that the present application can be used more widely. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] like Figure 1-2 As shown, a bridge crane track quick-changing device includes a track 1, a gantry 2, and a track trolley 3. The number of the track 1, the gantry 2, and the track trolley 3 are two. The track trolley 3 is respectively mounted on the track 1. The track trolley 3 includes a side panel 31. The number of the side panels 31 is two. Intermediate panels 32 are fixed on both sides of the side panels 31. Side support rods 33 are fixed on the bottom of the intermediate panels 32. The side support rods 33 are respectively located on the track 1 at matching positions. Wheel bodies 34 are provided between the side panels 31. Two support rods 38 are fixed on one end of the bottom of the side panel 31 close to the wheel body 34. Support cylinder members 36 are fixed at the position of the support rods 38 at the bottom of the wheel body 34. The support rods 38 are respectively penetrated and communicated with the support cylinder members 36 at matching positions.
[0018] Specifically, the outer diameter of the support rod 38 matches the inner diameter of the support cylinder 36 .
[0019] Specifically, the bottom of the support cylinder 36 is threadedly connected to the limiting screw 37 , and one end of the limiting screw 37 is respectively inserted into the interior of the support cylinder 36 and contacts the bottom of the support rod 38 .
[0020] Specifically, baffles 35 are fixed at both ends of the top of the wheel body 34 .
[0021] Working principle: a hand hoist needs to be installed on the gantry 2, and the track trolley 3 is placed on the two tracks 1. When placing, the distance between the side panels 31 on both sides of the track trolley 3 is adjusted according to the width between the tracks 1, and the support rod 38 is slid in the support cylinder 36 and moved left and right, so that the distance between the side panels 31 and the wheel body 34 is adjusted. After the adjustment is completed, the support rod 38 is limited by the limit screw 37, and then the side support rod 33 can be placed on the track 1. The new and old tracks 1 that need to be disassembled and installed are lifted by the hand hoist to between the baffles 35 on the top of the wheel body 34, and transported to the designated loading and unloading position by the movement of the side support rod 33 on the track 1, and then the new and old wall cabinets between the baffles 35 are loaded and unloaded by the hand hoist of the gantry 2 at the loading and unloading position.
