Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to a transport caster used for an updated escalator. Background Art

[0002] The truss in the escalator is the most basic load-bearing and supporting component, and is also the largest and heaviest component. Generally, the service life of an escalator is about 30 years. Escalators that have exceeded their service life need to be replaced. The replacement plan for existing escalators requires the removal of all the components of the original escalator and the installation of new escalators. However, the buildings where the escalators are replaced are usually still in normal use, and the components of the escalator are generally heavy. Both the removal of the original escalator and the installation of the new escalator require the use of large lifting equipment to transport the components, which makes the construction difficult.

[0003] In response to the problems existing in the existing escalator replacement solutions, the art has proposed an escalator replacement solution that retains the original truss, that is, using an updated escalator, removing the original escalator components except the truss during installation, and then installing the new escalator components in combination with the original truss. During the replacement process, there is no need to disassemble and transport the truss with the largest volume and weight, which can greatly reduce the cost of replacing the escalator and facilitate installation and construction. Since the components of the escalator except the truss are generally large in size and heavy in weight, manual transportation is very difficult, so usually a transportation auxiliary tool or a transport vehicle is used to transport the parts. The transport vehicles of some updated escalators in the prior art are relatively complex in structure, large in size and heavy in weight, which are inconvenient to use, resulting in low efficiency in the transportation and installation of escalator components. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when installing new escalator parts, it is difficult to carry them manually because the parts are generally large in size and heavy in weight, and some transport vehicles in the prior art have complex structures and heavy overall weight, which affects the installation efficiency of the escalator parts.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a transport caster for a newer escalator, comprising a front caster mounting structure symmetrically arranged on one side of an embedded module, and a rear caster mounting structure symmetrically arranged on one side of the embedded module away from the front caster mounting structure;

[0006] The front caster mounting structure comprises a front caster mounting plate, and a front caster mounting hole is arranged at a position at the bottom of the front caster mounting plate away from the embedded module;

[0007] The rear caster mounting structure comprises a rear caster mounting plate, a rear caster mounting hole is arranged at the bottom of the rear caster mounting plate away from the embedded module, and caster structures are installed in both the rear caster mounting hole and the front caster mounting hole;

[0008] The caster structure comprises a mounting shaft, a thread is arranged on the outer wall of the mounting shaft, a pad is arranged on the mounting shaft, and positions of the mounting shaft on both sides of the pad are threadedly connected with adjusting nuts, one of the adjusting nuts is pressed against the pad.

[0009] Through the above technical solution, the embedded module is a component of the escalator, and the transport casters can not only be used to transport the embedded module, but also can be used to transport other components of the escalator. Providing a pad at the connection of the adjusting nut can increase the contact area of ​​the connection, thereby dispersing the pressure applied by the adjusting nut to the connection part, reducing local stress concentration, and preventing loosening and deformation.

[0010] The utility model is further configured as follows: an outer ring wheel sleeve is provided on the mounting shaft, a positioning nut is provided on the side of the outer ring wheel sleeve close to the adjusting nut, the positioning nut is threadedly connected to the mounting shaft, a bearing is installed at a position of the mounting shaft located on the inner side of the outer ring wheel sleeve, a wheel hub is fixedly connected to the outer ring wheel sleeve by bolts, and a guide edge is provided on the side of the wheel hub close to the adjusting nut.

[0011] Through the above technical solution, the guide edge can enable the transport casters to use the original truss as a transport track, which facilitates the transportation of escalator parts and improves safety during transportation.

[0012] The utility model is further configured that the mounting shaft close to the front caster mounting plate is arranged in the front caster mounting hole, and the front caster mounting plate is arranged between the adjacent adjusting nut and the pad.

[0013] Through the above technical solution, by adjusting the position of the adjusting nut, the distance between the hubs on both sides can be adjusted to adapt to the size of the original truss.

[0014] The utility model is further configured that the mounting shaft close to the rear caster mounting plate is arranged in the rear caster mounting hole, and the rear caster mounting plate is arranged between the adjacent adjusting nut and the pad.

[0015] The utility model is further configured as follows: a plurality of first fixing holes are provided at the top of the front caster mounting plate, a clamping plate is provided at a position of the front caster mounting plate near the first fixing hole, connecting holes are provided at positions of the clamping plate near the first fixing hole, the clamping plate is fixedly connected to the front caster mounting plate by passing bolts through the connecting hole and the first fixing hole, a fourth fixing hole is provided at a position of the clamping plate near the embedded module, the clamping plate is fixedly connected to the embedded module by passing bolts through the fourth fixing hole, a second fixing hole is provided at the bottom of the front caster mounting plate, the front caster mounting plate is fixedly connected to the embedded module by passing bolts through the second fixing hole, and a plurality of first weight-reducing holes are provided on the front caster mounting plate.

[0016] Through the above technical solution, the weight-reducing holes are opened to reduce the overall weight of the transport casters, making it easier to disassemble and install the transport casters, thereby improving the convenience of using the transport casters.

[0017] The utility model is further configured such that a plurality of fifth fixing holes are provided at the top and bottom positions of the rear caster mounting plate, the rear caster mounting plate is fixedly connected to the embedded module by passing bolts through the fifth fixing holes, and a plurality of second weight-reducing holes are provided on the rear caster mounting plate.

[0018] The beneficial effects of the utility model are as follows:

[0019] The utility model utilizes the structure of the escalator parts themselves as a part of the transport structure, and utilizes the original truss as the transport track, which is convenient for transporting and installing the escalator parts and helps to improve safety at the same time; the transport caster has a simple structure and is light in overall weight, which is convenient for installation and use, so that the transport caster can be quickly installed on site, which improves the convenience of using the transport caster and improves the installation efficiency of the escalator parts; at the same time, the hub spacing of the transport caster can be adjusted according to the size of the original truss, and has strong applicability.
