Technical Field

[0001] The utility model relates to the technical field of auxiliary maintenance equipment for fracturing vehicles, and in particular to an assembly of a maintenance platform for a fracturing vehicle. Background Art

[0002] A fracturing truck is a special vehicle used to inject high-pressure, large-volume fracturing fluid into a well to break up the formation and squeeze proppant into the cracks. It is usually used online.

[0003] The fracturing truck plunger pump is the main working machine of the fracturing truck. On-site construction has very high requirements on the technical performance of the fracturing truck. The fracturing truck must have the characteristics of high pressure, large displacement, corrosion resistance, and strong wear resistance. Therefore, in order to ensure the working performance of the fracturing truck plunger pump, it is necessary to jack up the fracturing truck plunger pump for maintenance. During the maintenance of the fracturing truck plunger pump, the fracturing truck plunger pump is at a certain height from the ground, and it is necessary to climb to the fracturing truck manually. However, there are many equipment on the fracturing truck and the space is small. It is difficult for maintenance personnel to stand firmly during operation, resulting in difficult maintenance operations and low efficiency.

[0004] In the prior art, there is a patent document with publication number CN217966986U and patent name "A fracturing vehicle plunger pump maintenance platform". In this document, a telescopic platform is set up and the movement of the maintenance platform is driven by a cylinder to achieve outward expansion of the carriage, thereby supporting the maintenance personnel and improving the safety of maintenance.

[0005] However, there are still some shortcomings in the use process:

[0006] 1. The driving cylinder generally needs to be used in conjunction with an oil circuit and a control system. The fracturing truck is large in size and it is difficult to achieve precise control. There are also requirements for the connection accuracy of the driving cylinder, and the failure rate is high.

[0007] 2. The height of the fracturing truck is relatively high. During maintenance, it is difficult for operators to climb directly to the maintenance platform without an auxiliary ladder. The auxiliary ladder and the maintenance platform are generally independent, inconvenient to place, and will take up a certain amount of space. Utility Model Content

[0008] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a fracturing vehicle maintenance platform assembly, which simplifies the installation steps by improving the maintenance platform, further improves the practicability of the equipment, and reduces the maintenance cost of the equipment.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a fracturing vehicle maintenance platform assembly, including a fixed frame and a maintenance platform, the fixed frame is fixedly connected to the car body; the fixed frame is hollow, and a first slide is provided in the fixed frame, and two sides of the maintenance platform slide on the first slide respectively, and each of the slides is provided with a supporting roller for supporting the maintenance platform; a second slide is provided in the maintenance platform, and an auxiliary ladder slides in the second slide.

[0010] Preferably, a hanging ear is further provided at one end of the auxiliary ladder, and the maintenance platform is fixedly provided with a hanging shaft adapted to the hanging ear.

[0011] Preferably, the hanging ear is located on the upper end surface of the auxiliary ladder, and the maintenance platform is further provided with a limit plate for limiting the rotation angle of the auxiliary ladder, and the second slideway is formed between the limit plate and the maintenance platform.

[0012] Preferably, the auxiliary ladder is fixedly provided with a handle, and the position height of the opening groove on the suspension ear is flush with the height of the suspension shaft.

[0013] Preferably, the second slideway is perpendicular to the first slideway.

[0014] Preferably, the inspection platform and the fixing bracket are provided with matching limiting holes, and a locking pin for limiting the inspection platform is inserted into the limiting hole.

[0015] Preferably, a damping plate is further provided between the maintenance platform and the first slideway.

[0016] Preferably, the maintenance platform is provided with a plurality of guardrails, and protection chains are suspended between the guardrails.

[0017] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0018] 1. Since the fixed frame is hollow and a first slide is provided, the maintenance platform is slidably connected to the first slide, so that the maintenance platform can be pulled out when in use, reducing the occupied volume. At the same time, a second slide is provided on the maintenance platform, and an auxiliary ladder slides in the second slide. By hanging the auxiliary ladder to the suspension shaft, it is convenient for maintenance personnel to quickly climb to the maintenance platform, and the auxiliary ladder does not occupy additional space, increasing the practicality of the equipment.

[0019] 2. The auxiliary ladder is connected to the suspension shaft through the suspension ear located on the upper end surface of the auxiliary ladder, and the maintenance platform is also provided with a limit plate for limiting the rotation angle of the auxiliary ladder. In this way, when the auxiliary ladder is pulled to a certain extent, the suspension ear will be directly hung on the suspension shaft, and after rotating a certain angle, it will be fixed by the limit plate. The structure is simple and the stability is strong, so that the staff will feel more stable when stepping on it. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] See also Figure 1-Figure 4The utility model provides an assembly of a maintenance platform 2 for a fracturing vehicle, characterized in that it comprises a fixed frame 1 and a maintenance platform 2, wherein the fixed frame 1 is fixedly connected to the vehicle compartment; the fixed frame 1 is hollow, and a first slideway 21 is provided inside the fixed frame 1, and both sides of the maintenance platform 2 slide on the first slideway 21 respectively, and each slideway is provided with a support roller 22 for supporting the maintenance platform 2; a second slideway 23 is provided in the maintenance platform 2, and an auxiliary ladder 24 slides inside the second slideway 23. The fixed frame 1 is generally fixed directly to the vehicle compartment of the fracturing vehicle, and the fixed frame 1 is generally made of square steel, which is slotted as the first slideway 21, and a support roller 22 is provided in the first slideway 21 to support the maintenance platform 2. At the same time, a movable bearing is also provided at one end of the maintenance platform 2 to ensure the stability of movement. The inspection platform 2 is generally formed by welding with standard square steel, and limit plates 12 are set on both sides. One function of the limit plate 12 is to serve as the second slide 23 for placing the auxiliary ladder 24. Another function is that when the auxiliary ladder 24 is in the open state, although the top of the auxiliary ladder 24 is suspended on the rotating shaft, it will still swing. At this time, the limit plate 12 can prevent its rotation angle from being too large, and ensure a small tilt, which is convenient for operators to go up and down. The inspection platform 2 is fixed with a suspension shaft 11 that is compatible with the suspension ear 241. The auxiliary ladder 24 is connected to the suspension shaft 11 through the suspension ear 241, and cooperates with the limit plate 12 to ensure a certain tilt angle, which is convenient for climbing the auxiliary ladder 24.

[0028] The auxiliary ladder 24 of the utility model is fixed with a handle, and the position height of the opening slot on the hanging ear 241 is flush with the height of the hanging shaft 11. When the auxiliary ladder 24 needs to be opened, the handle is pulled to move the auxiliary ladder 24 along the second slide 23. When the hanging ear 241 contacts the hanging shaft 11, it will be stuck. After the auxiliary ladder 24 rotates downward at a certain angle, it abuts against the limit plate 12. At this time, the lower end of the auxiliary ladder 24 should almost abut the ground.

[0029] The second slideway 23 of the utility model is perpendicular to the first slideway 21. In order to reduce the occupied space and not interfere with the movement of the maintenance platform 2, the first slideway 21 and the second slideway 23 are perpendicular.

[0030] The maintenance platform 2 of the utility model is provided with matching limiting holes 13 on the fixing frame 1, and a locking pin 14 for limiting the maintenance platform 2 is inserted into the limiting hole 13. The locking pin 14 has two functions. One is to directly temporarily fix the maintenance platform 2 to the fixing frame 1 when the maintenance platform 2 is in a closed state. When the maintenance platform 2 is in an open state, the locking pin 14 is inserted again to prevent the maintenance platform 2 from sliding automatically, thereby improving the safety factor.

[0031] A damping sheet 25 is also provided between the maintenance platform 2 of the present invention and the first slideway 21. The material of the damping sheet 25 is generally synthetic rubber or synthetic fiber, and the speed of pushing and pulling the maintenance platform 2 will be more stable.

[0032] The maintenance platform 2 of the present invention is provided with a plurality of guardrails 15, and a protection chain 16 is suspended between the guardrails 15. The protection chain 16 is generally installed last to effectively prevent the operator from slipping and falling. In addition to the protection chain 16, a protection plate is generally provided to protect the maintenance tools.

[0033] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
