Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer machine technology, specifically to a portable transfer machine temporary support bracket. Background Technology
[0002] After the tunneling and anchoring machine and the transfer machine are de-energized and locked, workers will work and pass under them. The transfer machine has a large suspended area, which poses a significant threat to the workers. Furthermore, prolonged suspension can easily cause metal fatigue in the transfer machine, reducing its service life. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a portable temporary support bracket for a transfer machine. The bracket has a simple structure, low cost, strong practicality, and is easy to carry.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A temporary support bracket for a portable transfer machine includes a first steel plate 1, a second steel plate 2, a third steel plate 5, a first channel steel 3, and a second channel steel 4;
[0006] The first steel plate 1 and the second steel plate 2 are arranged in parallel and vertical positions.
[0007] The first channel steel 3 extends between the first steel plate 1 and the second steel plate 2 and is connected by bolts;
[0008] A second channel steel 4 is provided below the first channel steel 3, and a third steel plate 5 is placed horizontally at the bottom of the second channel steel 4.
[0009] The first steel plate 1, the second steel plate 2, and the third steel plate 5 are all 10mm thick. The second steel plate 2 and the first channel steel 3 are connected by two bolts with a diameter of 22mm.
[0010] The first steel plate 1 and the second steel plate 2 overlap with the first channel steel 3 by 10mm to ensure stability.
[0011] The first channel steel 3 and the second channel steel 4 are arranged vertically and fixed by bolts with a diameter of 22mm; the overlap length between the first channel steel 3 and the second channel steel 4 can be adjusted, with four levels of overlap length: 50mm, 130mm, 180mm and 260mm.
[0012] Four bolt holes are reserved between the first channel steel 3 and the second channel steel 4 for adjusting the height of the support frame. The first bolt hole is 50mm from the end of the second channel steel 4, and the spacing between the remaining bolt holes is 80mm.
[0013] The first channel steel 3 is located above the second channel steel 4, and a 10mm thick third steel plate 5 is horizontally welded to the bottom of the second channel steel 4. This ensures that the support frame has a sufficiently large foundation area with the ground when in use, increasing the stability of the support.
[0014] Two sets of bolt holes with a diameter of 22mm are provided on the first steel plate 1 and the second steel plate 2. The distance between the two sets of bolt holes is 145mm, and the distance between the bolt holes in each set is 90mm. The size is evenly distributed at the four corners of the first steel plate 1 and the second steel plate 2. The upper and lower bolt holes ensure that the distance between the holes in the steel plate and the middle length matches the cantilever of the transfer machine, ensuring that the steel plate can clamp the cantilever.
[0015] The beneficial effects of this utility model are:
[0016] This invention provides effective support for the transfer machine by installing a support frame, thereby improving the safety of personnel walking under the transfer machine.
[0017] This invention, by supporting the transfer machine, can reduce the shear stress inside the machine body, reduce metal fatigue, and thus extend the service life of the transfer machine. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of an embodiment of the present invention.
[0019] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] like Figure 2 As shown, a temporary support bracket for a portable transfer machine includes a first steel plate 1, a second steel plate 2, a third steel plate 5, a first channel steel 3, and a second channel steel 4;
[0022] The first steel plate 1 and the second steel plate 2 are arranged in parallel and vertical positions.
[0023] The first channel steel 3 extends between the first steel plate 1 and the second steel plate 2 and is connected by bolts;
[0024] A second channel steel 4 is provided below the first channel steel 3, and a third steel plate 5 is placed horizontally at the bottom of the second channel steel 4.
[0025] The first steel plate 1, the second steel plate 2, and the third steel plate 5 are all 10mm thick. The second steel plate 2 and the first channel steel 3 are connected by two bolts with a diameter of 22mm.
[0026] The first steel plate 1 and the second steel plate 2 overlap with the first channel steel 3 by 10mm to ensure stability.
[0027] The first channel steel 3 and the second channel steel 4 are arranged vertically and fixed by bolts with a diameter of 22mm; the overlap length between the first channel steel 3 and the second channel steel 4 can be adjusted, with four levels of overlap length: 50mm, 130mm, 180mm and 260mm.
[0028] Four bolt holes are reserved between the first channel steel 3 and the second channel steel 4 for adjusting the height of the support frame. The first bolt hole is 50mm from the end of the second channel steel 4, and the spacing between the remaining bolt holes is 80mm.
[0029] The first channel steel 3 is located above the second channel steel 4, and a 10mm thick third steel plate 5 is horizontally welded to the bottom of the second channel steel 4. This ensures that the support frame has a sufficiently large foundation area with the ground when in use, increasing the stability of the support.
[0030] Two sets of bolt holes with a diameter of 22mm are provided on the first steel plate 1 and the second steel plate 2. The distance between the two sets of bolt holes is 145mm, and the distance between the bolt holes in each set is 90mm. The size is evenly distributed at the four corners of the first steel plate 1 and the second steel plate 2. The upper and lower bolt holes ensure that the distance between the holes in the steel plate and the middle length matches the cantilever of the transfer machine, ensuring that the steel plate can clamp the cantilever.
[0031] The steel plate fixed to the transfer machine measures 280mm × 150mm × 10mm, ensuring sufficient contact area with the transfer machine's cantilever while maintaining aesthetic harmony. The base support steel plate measures 120mm × 120mm × 10mm, ensuring sufficient contact area while avoiding excessive size.
[0032] like Figure 1 As shown, this utility model mainly addresses the issue of personnel having to pass under the transfer conveyor when it is locked due to a power outage at the tunneling face, both on the pedestrian and non-pedestrian sides. To improve safety and extend the service life of the transfer conveyor, this is achieved by installing a temporary support bracket. This tool primarily supports the transfer conveyor, reducing its overhanging area, thereby providing necessary support and enhancing personnel safety when passing under it.
[0033] The support frame consists of three main parts: the first part is made of two parallel 10mm thick steel plates; the second part is made of a single No. 12 channel steel; and the third part is made of No. 10 channel steel welded perpendicularly to the 10mm thick steel plate.
[0034] These three parts are connected from top to bottom by bolts.
[0035] The working principle of this utility model is as follows:
[0036] Two temporary support brackets are installed at the bottom of the transfer machine, one on the pedestrian side and one on the non-pedestrian side.
[0037] Supporting function
[0038] Transfer conveyor support frames typically have a robust structure that distributes the weight of the transfer conveyor evenly onto the ground or other supporting foundation through its own frame and supporting components. This prevents the transfer conveyor from sinking, deforming, or tipping due to its own weight and the weight of the materials being transported, ensuring the stability of the transfer conveyor during operation.
[0039] Adjust height and angle
[0040] By adjusting the height, the transfer conveyor can achieve a smooth connection with upstream and downstream equipment, ensuring that materials can be transferred smoothly between different devices. Adjusting the angle, on the other hand, can adapt to different working environments and material conveying requirements.
[0041] Buffering and shock absorption
[0042] During the operation of the transfer machine, impact forces and vibration forces are generated due to factors such as material impact and equipment vibration. The support frame can absorb and mitigate some of these impact forces and vibration forces, reducing damage to the transfer machine and surrounding equipment, and also reducing the impact of noise and vibration on the working environment.
[0043] Easy to move and position
[0044] It can be easily moved to a new work site along with the transfer machine, and accurately fixed in the required position by the positioning device, which improves the flexibility and adaptability of the equipment.
