Description

Technical Field

[0001] This utility model belongs to the field of open wagon floor pressing technology, specifically relating to an open wagon floor pressing device. Background Technology

[0002] When replacing the floor of an open wagon, after the floor is laid, a crane is needed to lift a 3-ton iron weight. The base of the iron weight has a pressing area of ​​0.6 square meters. Using the weight of the iron weight, the floor is tightly fitted to the small and large crossbeams of the underframe. Then, a welder performs the welding operation. This process is repeated more than 40 times to finally complete the floor installation and welding replacement of the entire wagon. During the floor installation and welding process, the crane needs to be used throughout. Frontline workers have to repeatedly direct the crane to lift and lower more than 40 times. The work efficiency is extremely low, the labor intensity is high, and there are significant safety hazards. It has now become a bottleneck process in the open wagon maintenance process. It also affects the subsequent welding, which also needs to be done with each pressing operation. Utility Model Content

[0003] The present invention aims to provide a flatbed pressing device for open wagons, which has high working efficiency, greatly reduces workload, and solves the problems of low maintenance efficiency and safety hazards caused by the traditional method of relying mainly on manual operation of cranes to lift iron weights for pressing.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a floor pressing device for open wagons, including a cylinder mounting bracket, a vehicle body hook symmetrically hinged to the cylinder mounting bracket, and cylinders arranged in an array on the cylinder mounting bracket. The cylinder mounting bracket includes side plates and a cylinder slide rail assembly. The side plates are arranged in two mirror-symmetrical configurations. The cylinder slide rail assembly is located between the two side plates and is longitudinally spaced. The side plates are provided with hook mounting seats facing outwards, which are connected to the end pins of the vehicle body hooks. The cylinder slide rail assembly includes front and rear mirrors. The slide rails and drag-reducing tubes are symmetrically arranged. The slide rails have a cross-section in the shape of a "6". The drag-reducing tubes are located in the groove structure of the slide rails and form a sliding space with a top side plane and a bottom side arc surface. The telescopic end of the air cylinder is placed downwards. The front and rear ends of the lower side plate of the fixed end of the air cylinder are respectively located in the corresponding sliding space. Thus, the air cylinder can be moved along the air cylinder slide rail assembly by manual pushing. When the air cylinder mounting bracket is placed on the open wagon floor, the car body hook is upside down on the bottom of the open wagon and can be pressed onto the open wagon floor by extending downwards through the telescopic end of the air cylinder mounting bracket.

[0005] As a preferred embodiment of the above solution, the vehicle body hooks are installed on the side panels in four mirror-symmetrical configurations, ensuring secure hooking on both sides. The ends of the vehicle body hooks are provided with arc-shaped structures for easy hooking.

[0006] A further preferred embodiment is that the air cylinder slide assembly comprises three sets, with four air cylinders installed at equal intervals in each set, ensuring the operation of twelve air cylinders and meeting the requirement that the floor area can be pressed in one operation. The operating area of ​​the pressing device is 3.5m².2 This allows the pressing process to be completed in one press.

[0007] A further preferred embodiment is that the resistance-reducing circular tube is made of seamless galvanized steel pipe, which is reasonably selected, has limited resistance, and facilitates the movement of the air cylinder.

[0008] Further preferably, the air cylinder mounting bracket is equipped with rollers at the four corners of its bottom, which facilitates hoisting onto an open wagon for precise movement, and the side plates are made of channel steel, which is a reasonable material selection.

[0009] The beneficial effects of this utility model are: (1) Compared with the method of mainly relying on manual operation of crane to lift iron weights for pressing, this application uses air cylinders arranged in an array on the air cylinder mounting frame. The air cylinders transmit pressure to the floor to achieve the purpose of replacing iron weights for pressing and also achieve automatic pressing. Moreover, compared with a single weight that can only press 0.6㎡ and requires more than 40 repetitions, multiple air cylinders can press a whole floor at the same time. Only two crane operations are required, and the single-vehicle floor pressing process can save about 30 minutes of operation time. At the same time, it avoids safety hazards during the lifting process.

[0010] (2) The slide section is shaped like the number "6". The drag-reducing circular tube is located in the slide groove structure and forms a sliding space with a top side plane and a bottom side arc surface. The bottom side of the sliding space has an arc surface structure, which can reduce the contact area when it contacts the lower side plate of the air cylinder, and the air cylinder can be manually pushed to slide. The top side of the sliding space has a plane structure, which can ensure that the air cylinder will not slide easily due to resistance when there is no external force pushing it. The design structure is ingenious and the concept is novel.

[0011] This utility model has the advantages of reducing operational safety hazards, significantly reducing workload, improving work efficiency, and fully ensuring pressing quality. Attached Figure Description

[0014] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0015] Combination Figure 1 — Figure 2 As shown, a car floor pressing device consists of an air cylinder mounting bracket 1, a car body hook 2 symmetrically hinged to the air cylinder mounting bracket 1, and air cylinders 3 arranged in an array on the air cylinder mounting bracket 1.

[0016] The air cylinder mounting bracket 1 consists of a side plate 11 and an air cylinder slide rail assembly 12.

[0017] The side panels 11 are arranged in two mirror images of each other.

[0018] The air cylinder slide rail assembly 12 is located between the two side plates 11 and is arranged longitudinally at intervals.

[0019] The air cylinder mounting bracket 1 has rollers at the four corners of its bottom.

[0020] The side plate 11 is provided with a hook mounting seat 111 that is connected to the end pin of the hook 2 on the vehicle body.

[0021] The air cylinder slide assembly 12 consists of a slide 121 arranged in a mirror image symmetrically at the front and rear, and a drag-reducing circular tube 122.

[0022] The cross-section of slide 121 is shaped like the number "6".

[0023] The drag-reducing circular tube 122 is located within the groove structure of the slide 121 and forms a sliding space with a top side plane and a bottom side arc surface.

[0024] Seamless galvanized steel pipe is preferred for the drag-reducing round tube 122.

[0025] The air cylinder slide group 12 preferably adopts three groups, and each group of air cylinder slide group 12 has four air cylinders 3 installed at equal intervals.

[0026] The working area of ​​the pressing device is 3.5m². 2 .

[0027] The vehicle body hook 2 is preferably installed in four mirror-symmetrical positions on the side plate 11, and the two ends of the vehicle body hook 2 are provided with arc-shaped structures.

[0028] When the air cylinder mounting bracket 1 is placed on the open wagon floor, the air cylinder mounting bracket 1 is precisely moved to the designed position by rollers, and the car body hook 2 is upside down on the bottom of the open wagon body, and can be pressed onto the open wagon floor by extending the telescopic end of the air cylinder mounting bracket 1 downwards.

[0029] The air cylinder 3 is positioned with its telescopic end facing downwards, and the front and rear ends of the lower side plate 31 of the fixed end of the air cylinder 3 are respectively located in the corresponding sliding space, so that the air cylinder 3 can be moved along the air cylinder slide group 12 by manual pushing.

[0030] The calculation is based on the formula F=PS, where the old cylinder diameter is 120mm, the on-site compressed air pressure is 0.5MPa, and a single cylinder can provide 2.45t of pressure. If the factory's compressed air can provide 0.6MPa, the pressure of a single cylinder can reach 3.5t.

[0031] The test was conducted on a single set of four cylinders to press the floor, with a working area of ​​1 square meter. The actual test showed that it could meet the process requirements and production needs, but the stability was insufficient and the working efficiency was low.

[0032] To improve work efficiency, enhance equipment stability, and increase the working area, three sets of cylinders in a row, totaling 12 cylinders, were used to test their functionality and performance. A comprehensive evaluation of the pressing effect and usage showed that they could meet the process and production requirements, improve product stability, significantly increase work efficiency, and expand the working area to 3.5㎡.
