Description

Technical Field

[0001] The utility model relates to the technical field of track construction auxiliary equipment, in particular to a replaceable wheel hub structure and a tunnel track translation trolley with the same. Background Art

[0002] As my country's infrastructure construction, including railways, highways, and water pipelines, enters a period of rapid development, the number of railway tunnels, highway tunnels, and water tunnels under construction is rapidly increasing, and the span and depth of tunnel excavation are constantly increasing. During tunnel construction, tunnels are generally transported on a single track, with some areas using double tracks. When transporting concrete tankers and material transport vehicles on the tracks, if the tankers and other material transport vehicles are not promptly transferred to the empty area outside the tracks, the track channel will be congested, seriously affecting subsequent transportation processes. In addition, the wheel hubs of the track-mounted trolleys are extremely susceptible to damage under high pressure and high-intensity load conditions. Therefore, solving the problem of rapid disassembly and replacement of the trolleys in tunnels is crucial for material transportation in tunnels.

[0003] A survey of existing domestic rail translation trolleys found that when the wheel hub of the existing rail translation trolley is damaged, the wheel hub is replaced as a whole, and the replaced "waste" is not effectively utilized. In addition, the optimization of the width, length, area of ​​the load panel and the load capacity of the rail translation trolley has not effectively solved the problem of rapid disassembly and rapid replacement when the wheel hub of the rail translation trolley is damaged. There is an urgent need for a replaceable wheel hub structure for the rail translation trolley in the tunnel.

[0004] Based on the above, the utility model proposes a replaceable wheel hub structure and a tunnel track translation trolley with the same, which fills the gap in the field of track construction auxiliary equipment in the rapid disassembly and rapid replacement of the track translation trolley wheel hub when it is damaged, and realizes the short-time, high-quality and high-efficiency maintenance operation of the track translation trolley, avoiding the impact of subsequent tunnel material transportation processes due to damage to the track translation trolley wheel hub in the tunnel, saving time, manpower and material resources. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a replaceable hub structure and a tunnel track translation trolley with the same. Through the coordinated cooperation of the hub steel wheel, the hub connecting steel plate, the hub support pin shaft, and the retaining spring of the hub support pin shaft, the replaceable hub structure of the tunnel track translation trolley can be quickly constructed.

[0006] In the first aspect, the utility model provides a replaceable hub structure, which is used for a track translation trolley in a tunnel, and specifically includes a hub steel wheel, a hub connecting steel plate, a hub support pin and a retaining spring, wherein one end of the hub support pin movably passes through the hub steel wheel to form a rolling unit, and the ends of adjacent rolling units are connected by the hub connecting steel plate, the hub support pin passes through the hub connecting steel plate and the hub steel wheel and is connected by a retaining spring, and multiple rolling units are connected to form a crawler-type rolling structure.

[0007] Furthermore, the replaceable hub structure is composed of 20 rolling units of the same size. The two sides of each two hub steel wheels are connected by a hub connecting steel plate in the shape of "∞". The hub support pin connects the hub steel wheel and the hub connecting steel plate through the reserved holes of the hub steel wheel and the hub connecting steel plate. At the same time, the reserved groove at the end of the hub support pin is fixed with a retaining spring, and butter is applied between the hub support pin and the hub steel wheel to ensure smooth rolling.

[0008] Furthermore, the elastic modulus of the material of the hub steel wheel, hub connecting steel plate, hub supporting pin and retaining spring is greater than 200 GPa.

[0009] Furthermore, the hub steel wheel, hub connecting steel plate, hub supporting pin and retaining ring are made of Q235 steel or Q345 steel.

[0011] Furthermore, the hub connection outer steel plate and the hub connection inner steel plate are of equal size.

[0012] In a second aspect, the present invention further provides a tunnel track translation trolley, which includes the replaceable hub structure described in any scheme in the first aspect.

[0013] Furthermore, it includes a translation trolley steel frame and a hub elliptical steel shaft connected thereto, the replaceable hub structure surrounds and wraps around the outside of the hub elliptical steel shaft of the translation trolley steel frame, and the hub steel wheel rolls in contact with the outer wall of the hub elliptical steel shaft.

[0026] The following is a further description of the replaceable wheel hub structure of the track translation trolley in the tunnel of the present invention in conjunction with the accompanying drawings, so that those skilled in the art can better understand the technical solution of the present invention. This embodiment is implemented based on the technical solution of the present invention, but the protection scope of the present invention is not limited to the following embodiments.

[0027] The replaceable wheel hub structure provided in this embodiment for the track translation trolley in the tunnel is as follows: Figure 1 As shown, the track translation trolley, which is composed of a hub steel wheel 1, a hub connecting outer steel plate 2, a hub connecting inner steel plate 3, a hub support pin 4, a hub support pin retaining spring 5, a translation steel frame, and a translation platform, can significantly improve the efficiency of track transportation in tunnels and significantly reduce the time required to replace damaged hubs, thereby ensuring the stable progress of subsequent construction processes and improving construction efficiency and work quality.

[0028] like Figure 1-3 As shown, a replaceable hub structure for a track-translating trolley in a tunnel comprises a hub steel wheel 1, a hub connecting steel plate, a hub supporting pin 4, and a retaining spring 5 for supporting the pin, wherein the hub connecting steel plate comprises a hub connecting outer steel plate 2 and a hub connecting inner steel plate 3, wherein the hub steel wheel 1 is connected to the hub connecting outer steel plate 2 and the hub connecting inner steel plate 3 through the hub supporting pin 4, and the end of the hub supporting pin 4 is fixed with a retaining spring 5, one end of each hub supporting pin 4 movably passes through the hub steel wheel 1 to form a rolling unit, and multiple rolling units are connected to form a crawler-type rolling structure, which serves as a replaceable hub structure for a track-translating trolley in a tunnel.

[0029] like Figure 4 As shown, the replaceable hub structure is a rolling structure composed of 20 hub steel wheels 1 of the same size. The end sides of every two hub steel wheels 1 are connected by a hub connecting steel plate in the shape of "∞" (hub connecting outer steel plate 2 and hub connecting inner steel plate 3). The hub support pin 4 connects the hub steel wheel 1 to the hub connecting steel plate through the reserved holes of the hub steel wheel 1 and the hub connecting steel plate (steel wheel support shaft hole 6, steel plate support shaft hole 7). At the same time, the groove reserved at the end of the support pin 4 is fixed with a retaining spring 5, and butter is applied between the support pin 4 and the hub steel wheel 1 to ensure smooth rolling.

[0030] As an optional embodiment of the present invention, the present invention provides a tunnel track translating trolley having the aforementioned replaceable hub structure. Specifically, the aforementioned replaceable hub structure is entirely "wrapped" around the elliptical steel shaft of the translating trolley's steel frame. The hub steel wheel 1 itself rolls on the elliptical steel shaft, causing the translating trolley to move as a whole on the track. It is understood that the tunnel track translating trolley described in this application is a common track trolley, and therefore this application does not provide illustrations of the relevant structure of the track trolley. The working principle of the movement of the track translation trolley in the tunnel in this application is: the translation trolley steel frame is fixedly connected to the hub elliptical steel shaft, and the outer peripheral surface of the end of the hub elliptical steel shaft is inserted into the replaceable hub structure. When the translation trolley steel frame is displaced under the drive of other driving sources, the hub elliptical steel shaft drives the replaceable hub structure to displace on the track. At this time, the hub steel wheel 1 of the replaceable hub structure is in rolling contact with the outer peripheral surface of the hub elliptical steel shaft, that is, the hub elliptical steel shaft does not rotate when the track translation trolley is displaced in the tunnel. The hub elliptical steel shaft cooperates with the replaceable hub structure to mainly support the translation trolley steel frame on the track.

[0031] In an optional embodiment of the present invention, the hub steel wheel 1, the hub connecting outer steel plate 2, the hub connecting inner steel plate 3, the hub supporting pin 4, and the retaining spring 5 of the hub supporting pin 4 can all be made of Q235 steel.

[0032] like Figure 5-8 As shown, the hub steel wheel 1, the hub connecting outer steel plate 2, the hub connecting inner steel plate 3, the hub supporting pin 4, and the retaining spring 5 of the hub supporting pin 4 in the present invention all adopt a modular design, that is, the hub steel wheel 1, the hub connecting outer steel plate 2, the hub connecting inner steel plate 3, and the hub supporting pin 4 of the four wheel hubs of the track translation trolley are of the same size in length, width, thickness, and reserved hole positions (steel wheel support shaft hole 6, steel plate support shaft hole 7). During component installation and subsequent maintenance, construction can be carried out quickly, accurately, efficiently, and energy-saving, thereby reducing the construction period.

[0033] When using the replaceable wheel hub structure of the tunnel track translation trolley of the present invention, that is, when the wheel hub of the tunnel track translation trolley is damaged and needs to be removed and replaced with a new one, first use the hydraulic jack to lift the translation trolley steel frame to a certain height, then remove the retaining spring 5 of the wheel hub support pin 4, and take out the wheel hub support pin 4 from the reserved holes (steel wheel support shaft hole 6, steel plate support shaft hole 7) of the wheel hub steel wheel 1 and the hub connecting steel plate (the wheel hub connecting outer steel plate 2 and the wheel hub connecting inner steel plate 3), then remove the damaged wheel hub connecting steel plate and the wheel hub steel wheel 1, replace them with a new wheel hub connecting steel plate and the wheel hub steel wheel 1, and finally install the wheel hub support pin 4 in the reserved holes of the wheel hub steel wheel 1 and the wheel hub connecting steel plate, and fix it with the retaining spring 5 of the support pin, and remove the hydraulic jack. By means of the coordinated cooperation of the hub steel wheel 1, the hub connecting steel plate, the hub supporting pin shaft 4 and the retaining spring 5 of the hub supporting pin shaft, the hub of the track translation trolley in the tunnel can be replaced, thereby reducing the construction man-hours caused by the need to repair and replace the damaged hub of the track translation trolley, avoiding the influence of concrete tankers and material transport trucks on subsequent construction processes due to the damage of the translation trolley wheel hub, saving the time for repair and replacement, reducing the difficulty of replacing the hub, and reducing the cost of replacing the hub.

[0034] Optionally, the replaceable hub structure of the present invention can replace the Q235 steel used to make the hub steel wheel 1, hub connecting outer steel plate 2, hub connecting inner steel plate 3, hub support pin 4, and the retaining spring 5 of the hub support pin 4 with Q345 steel. This improves the overall strength of the track translation trolley, allowing it to withstand greater loads and facilitate the transportation of high-density, large-volume materials. At the same time, the replaceable hub structure design of the tunnel track translation trolley is rationally designed for stress, safe and stable, and has simple installation steps when entering on-site construction operations. It is suitable for various types of tunnel track transportation environments, can significantly improve tunnel track transportation efficiency, and significantly reduce the time required to replace damaged hubs, ensuring the stable progress of subsequent construction processes, and improving construction efficiency and work quality.

[0035] In addition to the above embodiments, the present invention may also have other implementation methods; any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
