Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, in particular to a hydraulic support vehicle blocking system and an engineering vehicle. Background Art

[0002] In order to ensure the safety of mine auxiliary transportation, the structure of the explosion-proof rubber-tyred trackless vehicle is simplified and explosion-proofed on the model of a general vehicle. The braking device currently used still uses the friction between the working surface of the fixed element and the rotating element to generate braking torque. Since the force required for braking is generated by friction, a large amount of heat will be generated and the reaction is slow. The running thread is long, the structure is complex and there are many parts. Once the brake fails, the vehicle will be out of control, causing significant losses to personnel and property.

[0003] The underground mines suitable for explosion-proof trackless rubber-wheeled vehicles will inevitably face the challenges of mine humidity (various spray dust removal devices), slippery (mixture of water and coal dust), narrowness and steep slopes. Simplified vehicles that tend to be general vehicles cannot meet the requirements of such sloped roads with low friction. Enhancing the safety of auxiliary transportation is an important issue for mines to prevent and curb major safety accidents. Utility Model Content

[0010] A cover plate is connected to the top surface of the wear-resistant support plate, a first rotation space is formed in the cover plate, and one end of the support structure close to the wear-resistant support plate is rotatably arranged in the first rotation space.

A chamber connected to the hydraulic control device is formed inside the hydraulic main rod, and the piston rod moves inside the hydraulic main rod through the chamber. This structure makes the support rod more stable and smooth during the extension and retraction process. At the same time, the connection between the hydraulic support rod and the engineering vehicle is firm and reliable, which can effectively transmit force and ensure that the vehicle can be quickly and effectively supported in emergency braking.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Combine the following Figures 1 to 6 The utility model describes a hydraulic support vehicle blocking system and an engineering vehicle.

[0035] like Figures 1 to 4 As shown, this embodiment provides a hydraulic support vehicle blocking system, which is applied to an engineering vehicle 30 . The hydraulic support vehicle blocking system includes: a hydraulic control device (not shown), a wear-resistant support plate 20 and a hydraulic support rod 10 .

[0036] In this embodiment, the hydraulic control device is arranged on the engineering vehicle 30, and the hydraulic control device is generally arranged in the control room of the engineering vehicle 30; the bottom surface of the wear-resistant support plate 20 is provided with a flame-retardant and wear-resistant layer 210; the hydraulic support rod 10 includes a support structure 130, a piston rod 110 and a hydraulic main rod 120, and a chamber connected to the hydraulic control device is formed in the hydraulic main rod 120, one end of the piston rod 110 is movably arranged at one end of the hydraulic main rod 120 through the chamber, and the other end of the hydraulic main rod 120 is connected to the engineering vehicle 30, the other end of the piston rod 110 is movably connected to the support structure 130, one end of the support structure 130 is rotatably connected to the engineering vehicle 30, and the other end of the support structure 130 is movably connected to the top surface of the wear-resistant support plate 20.

[0037] In this embodiment, the hydraulic control device is arranged in the control room of the engineering vehicle 30. The hydraulic control device is the core component of the whole system, and is responsible for controlling the extension and retraction of the hydraulic support rod 10. The device generally includes components such as an electro-hydraulic controller, a sensor, and an actuator. By operating the control device, the driver can accurately control the movement of the hydraulic support rod 10, thereby realizing emergency braking or self-rescue of the vehicle.

[0038] Among them, the wear-resistant support plate 20 is an important component of the system, and a flame-retardant wear-resistant layer 210 is provided on its bottom surface. The flame-retardant wear-resistant layer 210 is made of a special flame-retardant wear-resistant material (such as rubber) and has good flame-retardant and wear-resistant properties. During emergency braking or self-rescue, the flame-retardant wear-resistant layer 210 on the wear-resistant support plate 20 contacts the ground, and friction is generated between the flame-retardant wear-resistant layer 210 and the ground to achieve braking of the vehicle. At the same time, the flame-retardant property of the flame-retardant wear-resistant layer 210 ensures that the support plate will not fail due to burning in extreme cases.

[0039] When the hydraulic control device drives the piston rod 110 to extend and retract in the hydraulic main rod 120 , the piston rod 110 will drive the wear-resistant support plate 20 to move up and down through the support structure 130 , thereby achieving support or braking of the vehicle.

[0040] During emergency braking or self-rescue, the driver can operate the hydraulic control device in the control room.

[0041] Initially, if Figure 5 As shown at A in the figure, the piston rod 110 is located in the chamber of the hydraulic main rod 120. The driver can quickly extend the piston rod 110 from the hydraulic main rod 120 by operating the hydraulic control device in the control room. Figure 5 As shown in B. The piston rod 110 extends from the hydraulic main rod 120, and the support structure 130 rotates, so that the wear-resistant support plate 20 moves up and down until the flame retardant and wear-resistant layer 210 on the wear-resistant support plate 20 contacts the ground, achieving emergency braking. Figure 5 As shown in C, when the piston rod 110 is further extended from the hydraulic main rod 120 (until the support structure 130 is perpendicular to the wear-resistant support plate 20), the braking resistance can be increased. At the same time, in this state, it is convenient for the engineering vehicle 30 (pitted, flat tire, etc.) to perform self-rescue or auxiliary maintenance. At the same time, by adjusting the extension length and angle of the hydraulic support rod 10 and the support structure 130, the vehicle can be effectively supported and fixed to prevent the vehicle from continuing to slide or roll.

[0042] The hydraulic support vehicle blocking system provided by the embodiment of the utility model realizes the emergency braking and self-rescue processing functions of the engineering vehicle 30 through the coordinated action of the hydraulic control device, the wear-resistant support plate 20 and the hydraulic support rod 10. The system has the advantages of simple structure, convenient operation, good braking effect, strong durability, etc., and is suitable for various engineering vehicle transportation and mining operations, and improves the safety and reliability of the vehicle.

[0043] In some embodiments, Figures 1 to 4As shown, the hydraulic support vehicle-blocking system also includes: a cover plate 40, the cover plate 40 is connected to the top surface of the wear-resistant support plate 20, a first rotation space is formed in the cover plate 40, and one end of the support structure 130 close to the wear-resistant support plate 20 is rotatably arranged in the first rotation space. This design makes the connection between the support structure 130 and the wear-resistant support plate 20 more flexible and can adapt to different ground conditions and braking requirements. When the piston rod 110 is extended, the wear-resistant support plate 20 rotates relative to the support structure 130, so that the wear-resistant support plate 20 can better fit the ground and improve the braking effect. At the same time, this design also enhances the durability and stability of the system and reduces failures caused by wear.

[0044] Specifically, a first spherical connector is provided at one end of the piston rod 110 close to the wear-resistant support plate 20 , and the first spherical connector is rotatably disposed in the first rotation space.

[0045] During emergency braking or self-rescue, the driver operates the hydraulic control device in the control room to quickly extend the piston rod 110. The support structure 130 is connected to the wear-resistant support plate 20 through the first spherical connector, and drives the flame-retardant and wear-resistant layer 210 on the wear-resistant support plate 20 to contact the ground and generate friction, thereby achieving braking of the vehicle. During the whole process, the first spherical connector of the piston rod 110 rotates in the first rotation space, and the support structure 130 and the wear-resistant support plate 20 rotate relative to each other, so that the wear-resistant support plate 20 can better fit the ground and improve the braking effect.

[0046] In addition, when the flame retardant and wear-resistant layer 210 on the wear-resistant support plate 20 contacts the ground, it can be supported by the component, which can facilitate the engineering vehicle 30 to perform self-rescue or auxiliary maintenance.

[0047] Furthermore, if Figures 2 to 4 As shown, an adhesive layer is also provided between the flame retardant and wear-resistant layer 210 and the wear-resistant support plate 20. By providing the adhesive layer, the connection strength and stability between the flame retardant and wear-resistant layer 210 and the wear-resistant support plate 20 are enhanced, and the safety and reliability of the system are further improved. The system has the advantages of simple structure, convenient operation, good braking effect, strong durability, etc., and is suitable for various engineering vehicle transportation and mining operations, and provides an effective solution for the safe transportation of vehicles and emergency self-rescue.

[0048] Among them, the two ends of the wear-resistant support plate 20 extend upward from the ground, and a protrusion 220 is formed at the two ends of the wear-resistant support plate 20. The two ends of the flame-retardant wear-resistant layer 210 extend and are fixed on the protrusion 220. This design not only enhances the overall structural strength of the wear-resistant support plate 20, but also provides a more stable support for the fixation of the flame-retardant wear-resistant layer 210. The two ends of the flame-retardant wear-resistant layer 210 extend and are fixed on the protrusion 220, and the connection between the flame-retardant wear-resistant layer 210 and the wear-resistant support plate 20 is ensured to be firm and reliable through appropriate fixing methods (such as glue, bolt connection, etc.). This fixing method can effectively prevent the flame-retardant wear-resistant layer 210 from falling off or shifting during braking, thereby ensuring the stability and reliability of the braking effect.

[0049] In some embodiments, Figure 6 As shown, in order to enhance the friction of the flame retardant and wear-resistant layer 210, a plurality of fish scale-like protrusions are provided on the side of the flame retardant and wear-resistant layer 210 away from the wear-resistant support plate 20. These fish scale-like protrusions have a unique shape and arrangement, which can increase the contact area with the ground, thereby generating greater friction during braking. This design enables the system to stop the vehicle more quickly and effectively during braking, thereby improving the braking effect.

[0050] In some embodiments, Figures 2 to 4 As shown, a second rotation space is formed on the support structure 130 , and a second spherical connector is provided at the other end of the piston rod 110 , and the second spherical connector is rotatably disposed in the second rotation space.

[0051] In this embodiment, by providing the second spherical connector and the second rotation space, the piston rod 110 can more easily drive the support structure 130 to move, so that the wear-resistant support plate 20 can be adjusted by using the support structure 130 .

[0052] The hydraulic support rod 10 corresponds to the wear-resistant support plate 20 one by one and is provided in plurality. This one-to-one configuration allows each wear-resistant support plate 20 to be independently adjusted in position. The driver can precisely adjust the contact position and angle between each wear-resistant support plate 20 and the ground by controlling the extension and retraction of each hydraulic support rod 10 according to actual needs.

[0053] The engineering vehicle can brake by multiple wear-resistant support plates 20. This design makes the system more flexible and adaptable. The driver can choose to use some or all of the wear-resistant support plates 20 for braking according to actual needs. When greater braking force is required, more wear-resistant support plates 20 can be activated, and through the synergy of multiple hydraulic support rods 10, faster and more effective braking can be achieved.

[0054] In addition, the provision of multiple wear-resistant support plates 20 can also disperse the force during braking and reduce the wear and damage to a single wear-resistant support plate 20. This helps to extend the service life of the system and reduce maintenance costs.

[0055] It should be noted that the hydraulic support brake system should be regularly inspected and maintained during use. Check whether the hydraulic support rod 10 is normally extended and retracted, whether the wear-resistant support plate 20 is worn or damaged, etc. Any problems found should be repaired or replaced in time to ensure the normal operation of the system and the braking effect.

[0056] Based on the above embodiments, Figures 1 to 6 As shown, in some embodiments, to facilitate the installation of the hydraulic support vehicle blocking system, the hydraulic support vehicle blocking system further includes: a support frame 50. The support frame 50 is fixed on the engineering vehicle 30, and the other end of the hydraulic main rod 120 is connected to the support frame 50.

[0057] Specifically, the support frame 50 is fixed on the engineering vehicle 30, and the bottom or side of the vehicle can usually be selected as the fixing point. The structural design of the support frame 50 needs to take into account factors such as the model, size and working environment of the engineering vehicle 30 to ensure that the support frame 50 can be firmly fixed on the vehicle and withstand the force generated during the braking process. Through the connection of the support frame 50, a stable support structure is formed between the hydraulic support rod 10 and the engineering vehicle, ensuring the reliability and stability of the braking effect. The installation process of the support frame 50 is relatively simple and can be flexibly adjusted according to the actual situation of the engineering vehicle. During installation, it is necessary to ensure that the connection between the support frame 50 and the engineering vehicle 30 is firm and reliable to prevent loosening or falling off during braking.

[0058] The embodiment of the utility model also provides an engineering vehicle, which can be one of vehicles such as a loader, an excavator, a bulldozer, a grader, a roller, a dump truck, etc.

[0059] The engineering vehicle is provided with a hydraulic support and vehicle blocking system, which includes: a hydraulic control device (not shown), a wear-resistant support plate 20 and a hydraulic support rod 10. The hydraulic control device is arranged on the engineering vehicle 30, and is generally arranged in the control room of the engineering vehicle 30; the bottom surface of the wear-resistant support plate 20 is provided with a flame retardant and wear-resistant layer 210; the hydraulic support rod 10 includes a support structure 130, a piston rod 110 and a hydraulic main rod 120, a chamber connected to the hydraulic control device is formed in the hydraulic main rod 120, one end of the piston rod 110 is movably arranged at one end of the hydraulic main rod 120 through the chamber, the other end of the hydraulic main rod 120 is connected to the engineering vehicle 30, the other end of the piston rod 110 is movably connected to the support structure 130, one end of the support structure 130 is rotatably connected to the engineering vehicle 30, and the other end of the support structure 130 is movably connected to the top surface of the wear-resistant support plate 20.

[0060] During emergency braking or self-rescue, the driver can operate the hydraulic control device in the control room. Figure 5 As shown at A in the figure, the piston rod 110 is located in the chamber of the hydraulic main rod 120. The driver can quickly extend the piston rod 110 from the hydraulic main rod 120 by operating the hydraulic control device in the control room. Figure 5 As shown in B. The piston rod 110 extends from the hydraulic main rod 120, and the support structure 130 rotates, so that the wear-resistant support plate 20 moves up and down until the flame retardant and wear-resistant layer 210 on the wear-resistant support plate 20 contacts the ground, achieving emergency braking. Figure 5 As shown in C, when the piston rod 110 is further extended from the hydraulic main rod 120 (until the support structure 130 is perpendicular to the wear-resistant support plate 20), the braking resistance can be increased. At the same time, in this state, it is convenient for the engineering vehicle 30 (pitted, flat tire, etc.) to perform self-rescue or auxiliary maintenance. At the same time, by adjusting the extension length and angle of the hydraulic support rod 10 and the support structure 130, the vehicle can be effectively supported and fixed to prevent the vehicle from continuing to slide or roll.

[0061] In summary, the hydraulic support vehicle blocking system and engineering vehicle provided by the embodiment of the utility model can realize emergency braking or self-rescue of the engineering vehicle by controlling the extension and retraction of the hydraulic support rod. Compared with the traditional mechanical operation, the hydraulic control method has higher sensitivity and reliability, can effectively deal with emergencies, and ensure the safety of vehicles and personnel.

[0062] Secondly, the design of the wear-resistant support plate enhances the durability and stability of the system. A flame-retardant and wear-resistant layer is set on the bottom surface of the wear-resistant support plate, which not only increases the friction coefficient between the support plate and the ground and enhances the braking effect, but also the flame-retardant properties enable the system to maintain good performance under extreme conditions such as high temperature or fire. In addition, the wear-resistant support plate has a sturdy structure and can withstand greater pressure and impact force, ensuring that it is not easily damaged during emergency braking or self-rescue.

[0063] Furthermore, the design of the hydraulic support rod makes the system have stronger load-bearing capacity and stability. A chamber connected to the hydraulic control device is formed inside the hydraulic main rod, and the piston rod moves inside the hydraulic main rod through the chamber. This structure makes the support rod more stable and smooth during the extension and retraction process. At the same time, the connection between the hydraulic support rod and the engineering vehicle is firm and reliable, which can effectively transmit force and ensure that the vehicle can be quickly and effectively supported in emergency braking.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
