Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a mining vehicle component mechanism, in particular to a mining vehicle beam mechanism. Background Art
[0002] Existing mining vehicles generally include a mobile body and a carriage mechanism arranged on the mobile body, wherein the mobile body includes a beam mechanism, a cab installed on the front side of the beam mechanism, several sets of wheels installed on the beam mechanism, and an engine for driving the wheels.
[0003] As the supporting part of the mobile vehicle body, the structural stability of the beam mechanism directly affects the safety and service life of the vehicle. The existing beam mechanism generally includes a group of longitudinal beams arranged in parallel, and transverse reinforcement pipes connected between the group of longitudinal beams. In order to ensure that the rigidity of the longitudinal beams is not damaged, at present, most of the transverse reinforcement pipes are no longer installed by penetrating the longitudinal beams, but are installed by sleeve-connecting the transverse reinforcement pipes through the limit pipes fixed on the sealing plate of the longitudinal beams. There is a very tricky problem with this installation method: due to the limitation of the installation space, the weld between the limit pipe and the transverse reinforcement pipe can only be set at one end of the longitudinal beam where the sealing plate is set. Once the weld between the limit pipe and the transverse reinforcement pipe cracks, the overall stability of the beam mechanism will be greatly challenged. In serious cases, it will lead to a major accident. Therefore, many off-road dump trucks still continue to use the traditional method of penetrating the longitudinal beam to install the transverse reinforcement pipes.
[0004] Therefore, the research of the utility model is to design a highly adaptable off-road dump truck which can effectively ensure that the rigidity of the longitudinal beam is not damaged and the connection stability between the longitudinal beam and the transverse reinforcement pipe is ensured, thereby ensuring the driving and transportation safety. Summary of the invention
[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a mining vehicle beam mechanism, which can effectively solve the technical problems existing in the above-mentioned prior art.
[0006] The technical solution of the utility model is:
[0007] A mining vehicle beam mechanism, comprising
[0008] A group of longitudinal beams, wherein the longitudinal beams are arranged in parallel, and the longitudinal beams include beam plates, and the upper and lower ends of the beam plates are respectively folded inwards and fixedly connected with corresponding sealing plates.
[0009] A plurality of transverse reinforcing pipe fittings are respectively provided with mounting holes at positions corresponding to the transverse reinforcing pipe fittings, and limiting pipe fittings whose inner ends are fixed to the inner side walls of the beam plate are respectively fixedly installed at the mounting holes, and corresponding guide holes are respectively opened on the upper and lower sides of the inner end portions of the limiting pipe fittings, and connecting plates adapted to the guide holes are respectively provided on the upper and lower sides of the transverse reinforcing pipe fittings, and limiting blocks located on the inner sides of the connecting plates are respectively fixedly connected to the beam plate, and under the limiting of the limiting blocks, a group of the assembled longitudinal beams are pressed inwardly by hydraulic stamping, and the connecting plate is bent outward, passes through the guide holes of the limiting pipe fittings, and is then clamped to the limiting pipe fittings, and the transverse reinforcing pipe fittings and the limiting pipe fittings, as well as the limiting pipe fittings and the sealing plates are fixedly connected by corresponding welds.
[0010] The upper and lower ends of the inner side walls of the beam plate are respectively fixed with corresponding fixing blocks, and the connecting plate is bent outwardly and passes through the guide hole of the limiting pipe piece and then abuts against the fixing block.
[0011] The outer ends of the fixing blocks are respectively abutted against the bending parts of the beam plate.
[0012] The folded parts of the beams and plates are respectively fixedly welded inwardly with corresponding clamping plates, and corresponding positioning pins are respectively movably inserted on the clamping plates. The connecting plates are respectively provided with corresponding limiting holes at positions corresponding to the positioning pins, and the inner ends of the positioning pins are respectively fixedly inserted into the limiting holes of the connecting plates.
[0013] The side of the locating pin facing the sealing plate is fixedly connected to a compression spring fixedly connected to the sealing plate. The locating pin is made of iron material. The locating pin is adsorbed by an electromagnet arranged on the outer side of the sealing plate so that the side of the locating pin facing the beam plate is spaced apart from the beam plate. After the connecting plate is bent outward into place, the electromagnet is powered off, and the locating pin is inserted into the limiting hole of the connecting plate under the push of the compression spring.
[0014] A plurality of corresponding reinforcing ribs are fixedly welded at intervals between the transverse reinforcing pipe fitting and the limiting pipe fitting, and the reinforcing ribs are fixedly welded to the sealing plate.
[0015] The upper and lower sides of the sealing plate are respectively fixed to the upper and lower ends of the beam plate by welding.
[0016] The inner end of the limiting pipe is fixedly connected to the inner side wall of the beam plate by welding.
[0017] Advantages of the utility model:
[0018] 1) The inner end of the position-limiting pipe of the utility model is fixedly connected to the inner wall of the beam plate, and the upper and lower sides of the inner end of the position-limiting pipe are respectively provided with guide holes. In addition, the upper and lower sides of the transverse reinforcing pipe of the utility model are respectively provided with connecting plates adapted to the guide holes. The connecting plates are limited by the position-limiting blocks fixed on the beam plate inside the connecting plates. Then, the assembled set of longitudinal beams are pressed inward by hydraulic stamping, so that the connecting plates are bent outward and pass through the guide holes of the position-limiting pipe and then snapped onto the position-limiting pipe. Finally, the transverse reinforcing pipe and the position-limiting pipe, as well as the position-limiting pipe and the sealing plate are fixedly connected by corresponding welds. In this way, the connecting plate buckle can be effectively formed on the basis of the original single weld fixation of the transverse reinforcing pipe, thereby effectively adding a stable connection point without passing through the longitudinal beam. The ultimate goal is to effectively ensure that the rigidity of the longitudinal beam is not damaged, and to ensure the stability of the connection between the longitudinal beam and the transverse reinforcing pipe, thereby effectively and significantly improving the driving and transportation safety of the utility model.
[0019] 2) The upper and lower ends of the inner side walls of the beam plate of the utility model are respectively fixed with corresponding fixing blocks, and the connecting plate is bent outward and passes through the guide hole of the limit pipe and then abuts against the fixing block, and the outer ends of the fixing block abut against the bend of the beam plate. In this way, during the operation of the vehicle, the force of the transverse reinforcement pipe of the utility model can be partially transmitted directly to the fixing block through the connecting plate, thereby significantly improving the integrity between the transverse reinforcement pipe and the longitudinal beam, so as to further improve the driving and transportation safety of the utility model.
[0020] 3) The folded parts of the beam and plate of the utility model are respectively fixedly welded inward with corresponding clamping plates, and corresponding positioning pins are respectively movably inserted on the clamping plates. The connecting plates are respectively provided with corresponding limiting holes at positions corresponding to the positioning pins. Through the setting of compression springs, the inner ends of the positioning pins can be respectively fixedly inserted into the limiting holes of the connecting plates. Under the action of the positioning pins, the bent connecting plates are further clamped, thereby further improving the integrity between the transverse reinforcement pipe and the longitudinal beam of the utility model, so as to further improve the driving and transportation safety of the utility model.
[0021] 4) Although the inner end of the positioning pin can be fixedly inserted into the limiting hole of the connecting plate by the setting of the compression spring, it will also hinder the bending process of the connecting plate. For this reason, the utility model further makes the positioning pin made of iron material, and then uses the electromagnet set on the outside of the sealing plate to adsorb the positioning pin, so that the side of the positioning pin facing the beam plate is spaced between the beam plate. After the connecting plate is bent outward in place, the electromagnet is controlled to be powered off, so that the positioning pin can be inserted into the limiting hole of the connecting plate under the push of the compression spring. In this way, the adverse effects brought about by the matching setting of the positioning pin and the compression spring can be effectively overcome, so as to further improve the practical effect of the utility model.

[0028] A group of longitudinal beams 1, wherein the longitudinal beams 1 are arranged in parallel, and the longitudinal beams 1 include beam plates 101, and the upper and lower ends of the beam plates 101 are respectively folded inwards and fixedly connected with corresponding sealing plates 102,
[0029] A plurality of transverse reinforcing pipe fittings 2 are provided with mounting holes at positions corresponding to the transverse reinforcing pipe fittings 2, and the sealing plates 102 are respectively provided with mounting holes, and the mounting holes are respectively fixed with limiting pipe fittings 3 whose inner ends are fixedly connected to the inner side walls of the beam plate 101, and the upper and lower sides of the inner ends of the limiting pipe fittings 3 are respectively provided with corresponding guide holes, and the upper and lower sides of the transverse reinforcing pipe fittings 2 are respectively provided with connecting plates 201 adapted to the guide holes, and the beam plate 101 is respectively fixedly connected with limiting blocks 4 located on the inner sides of the connecting plates 201, and under the limiting of the limiting blocks 4, the assembled group of longitudinal beams 1 are pressed inwardly by hydraulic stamping, and the connecting plates 201 are bent outwardly, penetrate through the guide holes of the limiting pipe fittings 3, and are clamped to the limiting pipe fittings 3, and the transverse reinforcing pipe fittings 2 and the limiting pipe fittings 3, as well as the limiting pipe fittings 3 and the sealing plates 102 are fixedly connected by corresponding welds 5.
[0030] The present invention effectively forms a connection plate 201 on the basis of the original single weld fixation of the transverse reinforcing pipe 2, thereby effectively adding a stable connection point without penetrating the longitudinal beam 1, thereby effectively ensuring that the rigidity of the longitudinal beam 1 is not damaged, and ensuring the stability of the connection between the longitudinal beam 1 and the transverse reinforcing pipe 2, thereby effectively and significantly improving the driving and transportation safety of the utility model.
[0031] The upper and lower ends of the inner side walls of the beam plate 101 are respectively fixed with corresponding fixing blocks 6, and the connecting plate 201 is bent outward and passes through the guide hole of the limiting pipe 3 and then abuts against the fixing block 6. The outer ends of the fixing blocks 6 abut against the bends of the beam plate 101. During the operation of the vehicle, the force of the transverse reinforcing pipe of the utility model can be partially transmitted directly to the fixing block through the connecting plate, thereby significantly improving the integrity between the transverse reinforcing pipe and the longitudinal beam, so as to further improve the driving and transportation safety of the utility model.
[0032] The folded parts of the beam plate 101 are respectively fixedly welded inwardly with corresponding clamping plates 7, and corresponding positioning pins 8 are respectively movably inserted on the clamping plates 7. The connecting plates 201 are respectively provided with corresponding limiting holes at positions corresponding to the positioning pins 8, and the inner ends of the positioning pins 8 are respectively fixedly inserted into the limiting holes of the connecting plates 201.

After the connecting plate 201 is bent outward into place, the electromagnet is powered off, and the locating pin 8 is inserted into the limiting hole of the connecting plate 201 under the push of the compression spring 9.
[0034] Although the inner end of the positioning pin 8 can be fixedly inserted into the limiting hole of the connecting plate 201 by the arrangement of the compression spring 9, it will also hinder the bending process of the connecting plate 201.

After the connecting plate 201 is bent outward in place, the electromagnet is controlled to be powered off, so that the positioning pin 8 is inserted into the limiting hole of the connecting plate 201 under the push of the compression spring 9.
