Description

Technical Field

[0001] This utility model relates to a longitudinal and transverse track conversion device, which is mainly used for track connection at the intersection of longitudinal and transverse tracks in a construction site. Background Technology

[0002] During construction, moving equipment often needs to cross paths within the construction site. When there are longitudinal and transverse tracks in the site, the moving equipment cannot pass through the intersection of the longitudinal and transverse tracks. It is necessary to install a universal connecting device for both longitudinal and transverse tracks to solve the problem of smooth passage for moving equipment.

[0003] Chinese patent application CN101575830A discloses a planar cross-track converter, which includes a base and a track rotator horizontally mounted on the base. A transition track is provided on the base outside the rotation area of ​​the track rotator. One end of the transition track is used to connect with the corresponding track at the track intersection, and the other end engages with the track rotator when it rotates to the intersection. A circumferential positioning self-locking mechanism is provided at the engagement point. A pressure block is slidably mounted in a through groove along the length of the top of the track rotator. An elastic reset device is provided between the bottom surface of the pressure block and the track rotator. When the pressure block slides under pressure, it drives the circumferential positioning self-locking mechanism to self-lock. Although the track converter in this patent document can automatically connect with the track in the direction of travel when a vehicle passes through a track intersection, allowing the vehicle to pass smoothly through the intersection, the track converter has a complex structure and requires a track fork to be installed at the front of the crossing device, making it unsuitable for installation and use on construction sites. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a longitudinal and transverse track conversion device with a simple structure that can effectively solve the problem of smooth passage of longitudinal and transverse machinery in construction sites.

[0005] This utility model is achieved through the following technical solution: a longitudinal and transverse track conversion device, installed at the intersection of transverse and longitudinal rails arranged in a cross shape, characterized in that: it includes a base plate device and a connecting rail device. The base plate device includes a base plate and four sets of slot baffles fixedly installed on the upper part of the base plate. The slot baffles are L-shaped structures, and the four sets of slot baffles form a cross-shaped slot on the upper part of the base plate. The base plate is fixed on the foundation at the intersection of the transverse and longitudinal rails, and the four slots of the cross-shaped slots on the base plate correspond to the rail heads of the transverse and longitudinal rails respectively. The connecting rail device includes a connecting rail and a rail seat that match the transverse and longitudinal rails. The rail seat is a cuboid structure that can cooperate with the slots on the base plate. The lower part of the connecting rail is fixedly connected to the rail seat. The connecting rail device is installed on the base plate device through its rail seat cooperating with the slots on the base plate.

[0006] In this invention, the rail connecting device uses a rail seat that engages with a slot on the base plate. After installation, the connecting rail can connect with either a transverse or longitudinal rail. Depending on the travel direction of the moving equipment, by engaging the rail seat of the connecting device with the corresponding slot on the base plate, the connecting rail can connect with the corresponding rail, allowing the moving equipment to pass smoothly through rail intersections. When it is necessary to change the direction of the connecting rail, the connecting device is lifted, rotated 90 degrees, and its rail seat is engaged with the slot in the other direction to connect the connecting rail with the rail in that direction.

[0007] Furthermore, the rail heads at the intersection of the transverse and longitudinal rails are fixedly connected as one unit by four diagonally arranged connecting steel plates. These connecting steel plates connect the rail heads at the intersection of the transverse and longitudinal rails, preventing rail head swaying and ensuring the safe passage of traveling machinery.

[0008] Furthermore, the connection point between the connecting steel plate and the rail is 100mm from the rail head.

[0009] Furthermore, the rail base includes vertical baffles vertically disposed on both sides of the base of the connecting rail and fixedly connected thereto, and transverse baffles fixedly connected between the vertical baffles and the web of the connecting rail, with the bottom of the vertical baffles flush with the bottom of the connecting rail.

[0010] The beneficial effects of this utility model are as follows: This utility model has a simple structure. Through the cooperation of the base plate device and the connecting rail device, it can easily realize the track conversion at the intersection of transverse and longitudinal rails, ensuring the smooth passage of traveling machinery within the site. The structural design of the base plate device and the connecting rail device in this utility model makes the direction conversion of the connecting rails simple, convenient, and quick. Furthermore, the base plate device is a fixed structure, and the connecting rail device cooperates with the slots on the base plate device, making the conversion device stable overall and the connecting rails highly stable, thus improving the safety of traveling machinery when passing through track intersections. By setting a connecting steel plate between the rail heads, the rail heads of the longitudinal and transverse rails can be connected as one unit, preventing rail head swaying at rail intersections and ensuring the safe passage of traveling machinery. This utility model has a simple structure, is easy to process and manufacture, and is reliable in use. It is very suitable for installation and use in engineering construction sites and can effectively solve the problem of smooth passage of longitudinal and transverse traveling machinery within the construction site.

Detailed Implementation

[0017] The technical solution of this utility model will be described in detail below through non-limiting embodiments and in conjunction with the accompanying drawings.

[0018] As shown in the attached figure, a longitudinal and transverse track conversion device is installed at the intersection of transverse rails 1 and longitudinal rails 2 arranged in a cross shape, with the rail head spacing at the intersection of the transverse rails 1 and longitudinal rails 2 being 300mm. The longitudinal and transverse track conversion device includes a base plate device and a rail connecting device 6. The base plate device includes a base plate 4 and four sets of slot baffles 5 fixedly installed on the upper part of the base plate 4. The base plate 4 is a 300×300×20mm steel plate, and the base plate 4 is fixed to the foundation at the intersection of the transverse rails 1 and longitudinal rails 1. Preferably, the base plate 4 is pre-embedded in the rail foundation at the intersection. The slot baffles 5 are L-shaped structures welded from steel plates and are welded to the base plate 4. Two adjacent sets of slot baffles 5 are symmetrically arranged with respect to the transverse rails 1 or longitudinal rails 2. The four sets of slot baffles 5 form a cross-shaped slot 7 on the upper part of the base plate 4, and the four slots of the cross-shaped slot 7 correspond to the rail heads of the transverse rails 1 and longitudinal rails 2, respectively. The height of the slot baffle 5 is 50mm. The connecting rail device 6 includes a connecting rail 6.1 and a rail seat. The connecting rail 6.1 is of the same type as the transverse rail 1 and the longitudinal rail 2, using a 43-type rail. The length of the connecting rail 6.1 is 300mm. The rail seat is a cuboid structure that can mate with the slot 7 on the base plate 4, and its length is 300mm. The lower part of the connecting rail 6.1 is fixedly connected to the rail seat. The connecting rail device is mounted on the base plate device through its rail seat mating with the slot 7 on the base plate 4. The connecting rail device can mate with the two vertical slots on the base plate 4 respectively, so that the connecting rail 6.1 can connect with the transverse rail 1 or the longitudinal rail 2 respectively. The slot baffle 5 on the base plate 4 can limit the movement of the connecting rail device and prevent it from shaking, ensuring its stability.

[0019] To prevent the rail heads from swaying at the rail intersections, it is preferable that the rail heads at the intersections of the transverse rail 1 and the longitudinal rail 2 are fixedly connected as one unit by four obliquely arranged connecting steel plates 3. The connecting steel plates 3 are welded to the rails, and the connecting steel plates 3 are made of 20mm thick steel plates. The distance between the connection point of the connecting steel plates 3 and the rails and the rail head is 100mm.

[0020] The rail base in this utility model can be a cuboid structure made of steel plate or shaped steel. For ease of manufacturing, the structure used in this embodiment is as follows: the rail base includes vertical baffles 6.2 vertically arranged on both sides of the base connecting the rail 6.1 and welded to it; and a transverse baffle 6.3 welded between the vertical baffles 6.2 and the web of the connecting rail 6.1, with the bottom of the vertical baffles 6.2 flush with the bottom of the connecting rail 6.1. The vertical baffles 6.2 are made of 20mm thick steel plate, and the height of the vertical baffles 6.2 is 50mm. The transverse baffles 6.3 are also made of 20mm thick steel plate. The vertical baffles, transverse baffles, and the base connecting the rail form a stable rail base.

[0021] When using this invention, according to the travel direction of the traveling machine, the rail seat of the connecting rail device is matched with the corresponding slot on the base plate 4, so that the connecting rail 6.1 can be connected with the corresponding rail, and the traveling machine can pass smoothly through the rail intersection; when it is necessary to change the direction of the connecting rail 6.1, the connecting rail device is lifted out and rotated 90 degrees, and its rail seat is matched with the slot in the other direction, so that the connecting rail 6.1 can be connected with the rail in the other direction.

[0022] This utility model has a simple structure and reliable use. Through the cooperation of the base plate device and the connecting rail device, the track conversion at the intersection of the transverse and longitudinal rails can be easily realized, ensuring the smooth passage of traveling machinery in the site. It is very suitable for installation and use in engineering construction sites and can effectively solve the problem of smooth passage of longitudinal and transverse traveling machinery in the construction site.

[0023] The other parts in this embodiment are all existing technologies and will not be described in detail here.
