Description
Technical Field
[0001] This application relates to the technical field of subway construction, and particularly to a rail support for rail transit construction. Background Art
[0002] The subway is a form of rail transportation, referring to an urban rail transit system mainly operating underground, namely the abbreviation of "underground railway" or "subway"; in order to match the construction environment and consider the construction and operation costs, many such systems may turn into ground or elevated sections outside the city center. The laying of subway tracks is an important link in subway construction. In traditional subway track laying, after laying the sleepers on the roadbed, construction workers lay the rails on the sleepers section by section in a way of manually lifting, and connect and fix the rails laid on them through the fasteners on the sleepers to ensure the stability of the rails. However, since the rails of the subway are made of solid metal structures and are relatively heavy, directly manually lifting the rails by manpower will cause hand fatigue to the construction workers after a long time, which is time-consuming and laborious and is not conducive to improving the laying efficiency of the rails. When the current device transports the rails, since the two ends of the rails are relatively sharp, accidents may occur during transportation, and the two ends of the rails are likely to cause harm to the staff. At the same time, the current device cannot be fixed after moving, and the inertia generated after moving may cause the device to get out of control. Therefore, it is necessary to design a rail support for rail transit construction. Content of the Utility Model

[0031] In view of the above problems, an embodiment of this application provides a rail support for rail transit construction. The technical solution of the embodiment of this application will be described in detail below with reference to the drawings.
[0032] As Figure 1 、 Figure 2 and Figure 3 shown, a rail support for rail transit construction includes: a protection mechanism, and the protection mechanism includes a support plate 1, a bidirectional threaded rod 3, a first turning handle 4, a first support rod 5, a first protective housing 6, a second support rod 7, a second protective housing 8, and a fixing plate 15;
[0033] Among them, two support plates 1 are symmetrically arranged on the fixing plate 15, a bidirectional threaded rod 3 is rotatably arranged between the two support plates 1, a first turning handle 4 is fixedly arranged in the middle of the bidirectional threaded rod 3, a first support rod 5 and a second support rod 7 are symmetrically and threadedly connected to the bidirectional threaded rod 3, one end of the first support rod 5 is connected to a first protective housing 6, and one end of the second support rod 7 is connected to a second protective housing 8.
[0034] In this way, the first support rod 5 and the second support rod 7 are located above the support plate 1 and in contact with the support plate 1. The protection mechanism drives the bidirectional threaded rod 3 to rotate by manually rotating the first handle 4, so that the first support rod 5 and the second support rod 7 on the bidirectional threaded rod 3 open or close to both sides. When operating on the rail, first open the first protective housing 6 and the second protective housing 8 on the first support rod 5 and the second support rod 7. After the rail is placed stably, then rotate the first handle 4 to sleeved the first protective housing 6 and the second protective housing 8 on both ends of the rail. In this way, the protective housing protects both ends of the rail to prevent injury to workers.
[0035] At the same time, this application also includes a clamping mechanism; the clamping mechanism includes a support plate 1, a telescopic rod 10, a spring 11, and a clamping plate 12; wherein, a groove 2 is constructed on the support plate 1, telescopic rods 10 are connected and arranged on both sides in the groove 2, the telescopic ends of the telescopic rods 10 are connected and arranged with the clamping plate 12, a spring 11 is sleeved on the telescopic rod 10, one end of the spring 11 abuts against the clamping plate 12, and the other end abuts against the groove 2; wherein, the clamping mechanism and the protection mechanism share a support plate 1.
[0036] In this way, the rail is first placed into the clamping mechanism and is clamped by the spring 11 driving the telescopic rod 10 and the clamping plate 12 thereon, so as to prevent it from moving left and right. Combining with the first protective housing 6 and the second protective housing 8 to protect the other two directions, thus achieving the purpose of both restricting the movement of the rail and protecting both ends to prevent injury to personnel.
[0037] In one embodiment, a single first support rod 5 and second support rod 7 can only sleeve one rail, and moreover, if the contact gap with the support plate 1 is too large, it will also rotate with the bidirectional threaded rod 3. Therefore, to avoid this, as Figure 2 shown, a slide rod 9 is arranged between the two support plates 1 on both sides. The first support rod 5 and the second support rod 7 are symmetrically arranged in three groups, two in each group. One group is threadedly connected to the bidirectional threaded rod 3, and the other two groups are respectively slidably connected to the slide rod 9. The first protective housing 6 and the second protective housing 8 are symmetrically arranged in two groups, two in each group, and are respectively connected between each group of first support rods 5 and each group of second protective housings 8.
[0038] In this way, one protection mechanism can not only protect two rails, but also make the operation of the whole mechanism smoother and avoid unnecessary adjustment.
[0039] In one embodiment, in order to be adapted to the protection mechanism for use, as Figure 3 shown, the grooves 2 on the support plate 1 are symmetrically arranged in two, and the clamping mechanisms are symmetrically arranged in two groups. The two groups of clamping mechanisms share a support plate 1.
[0040] In one embodiment, to better protect and limit the two ends of the rail, the first protective housing 6 and the second protective housing 8 are arranged as square protective grooves; the first support rod 5 and the second support rod 7 are arranged in the shape of a channel steel cross-section and are buckled on the support plate 1.
[0041] In one embodiment, to facilitate clamping and placing the rail, the upper part of the clamping plate 12 expands outwards, so that the upper halves of the two clamping plates 12 are in an inverted conical shape.
[0042] In one embodiment, when the rail is in use, it may also need to be adjusted up and down. For this reason, as Figure 4 shown, the present application further provides an auxiliary adjustment mechanism. The adjustment mechanism includes a sleeve 16, a threaded shaft 17, a second rotating handle 18, and a sliding seat 19;
[0043] Wherein, a sliding groove 14 is formed on one side of the support plate 1, the sliding seat 19 is slidably connected in the sliding groove 14, the sleeve 16 is fixedly arranged at the bottom of the fixing plate 15, the second rotating handle 18 is rotatably connected to the sleeve 16, and the threaded shaft 17 is fixedly arranged on the sliding seat 19 and is threadedly connected to the second rotating handle 18.
[0044] In this way, by rotating the second rotating handle 18, the threaded shaft 17 can be driven to rotate, so that the fixing plate 15 can be adjusted up and down.
[0045] In one embodiment, a moving wheel 20 is connected to the bottom of the sliding seat 19 to facilitate moving and adjusting.
[0046] In one embodiment, a push handle 13 is connected to one side of the support plate 1 to facilitate hand-held moving and adjusting.
[0047] Working principle of this device: During use, press the outer surface of the rail against the clamping plate 12 and press downwards. The telescopic rod 10 can be telescoped, and the rail can be placed in the groove 2. Through the setting of the spring 11, the clamping plate 12 can be rebounded to clamp the rail. After the rail is fixed, hold the first rotating handle 4 by hand and rotate it, which can drive the double-threaded rod 3 to rotate. Through the rotation of the double-threaded rod 3, the first support rod 5 and the second support rod 7 can move relatively or towards each other, and then the first protective housing 6 and the second protective housing 8 can be adjusted. The two ends of the rail can be protected by the first protective housing 6 and the second protective housing 8 to prevent injury to workers. When it is necessary to move, hold the second rotating handle 18 by hand and rotate it, which can drive the threaded shaft 17 to rotate, so that the threaded shaft 17 can be adjusted. When adjusting, the sliding seat 19 can slide along the sliding groove 14. At the same time, when the device needs to move, hold the push handle 13 by hand, and the device can be pushed and moved through the moving wheels 20.
[0048] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variation is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
