Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment of a fracturing vehicle, in particular to a ladder assembly of a fracturing vehicle. Background Art

[0002] In oil operations, in order to ensure a good oil yield, a fracturing truck is needed. As a special vehicle, the main function of a fracturing truck is to open the formation and squeeze the proppant into the cracks by injecting high-pressure, large-volume fracturing fluid into the well. This type of vehicle plays a vital role in the fracturing operations of oil, natural gas and water, and is used to increase the output of oil and gas fields. Fracturing trucks are generally used in multiples. Since there are a large number of electrical equipment and high-pressure pumps on the vehicle, frequent inspections and maintenance are required. The fracturing truck is large in size and needs to be equipped with an escalator to facilitate operators to get on and off.

[0003] In the prior art, there is a patent document with a patent announcement number of CN206346696U, and the patent name is a patent document of a foldable escalator for a fracturing truck. In the patent document, a foldable escalator consisting of a handrail, a fixed beam, an upper escalator, a cross plate and a lower escalator is provided to solve the problem of inconvenience for workers to go up and down. However, during use, there are still the following shortcomings:

[0004] 1. The space in the pressure vehicle is limited, and the positions of various pump bodies are generally fixed. It is difficult to set up a certain space in a horizontal carriage to place a folding escalator. The practicality of the above patent is not strong.

[0005] 2. When the fracturing truck is working, some pipe joints cannot be well sealed, so some mortar will overflow into the slideway, and it is difficult to clean it in time. When the above patent is in use, if the slideway is easily mixed with mud, it will cause unsmooth sliding, and pulling failures are prone to occur during use. Utility Model Content

[0006] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a fracturing truck ladder assembly, which reduces the occupied space and facilitates operators to go up and down by providing a vertically foldable main ladder and an auxiliary ladder.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a fracturing truck ladder assembly, comprising a fracturing truck body, a main ladder and an auxiliary ladder, the carriage of the fracturing truck body is fixedly provided with a connecting base connecting the main ladder and the auxiliary ladder; the fracturing truck body is provided with a spare tire platform, the upper end of the main ladder is hinged to the spare tire platform, and the lower end is hinged to the connecting base; the auxiliary ladder is located on one side of the main ladder, one end of the auxiliary ladder is hinged to the connecting base, and the other end abuts against the ground when the auxiliary ladder is in an open state; the main ladder is also provided with a limiting device, and the limiting device is used to keep the auxiliary ladder in a vertical closed state and fixed.

[0008] Preferably, the limiting device is a knob plunger, and the auxiliary ladder is provided with a limiting plate adapted to the knob plunger.

[0009] Preferably, the auxiliary ladder is also provided with an anti-collision pad, and the anti-collision pad is close to one side of the fracturing vehicle body.

[0010] Preferably, the widths of both sides of the anti-collision pad are the same as those of the auxiliary ladder, and the anti-collision pad is in a wedge shape that is wider at the top and narrower at the bottom.

[0011] Preferably, a plurality of grooved pedals are welded to the middle of the main ladder and the auxiliary ladder, and a plurality of rectangular teeth are provided on the top of each of the grooved pedals.

[0012] Preferably, a drainage hole is also provided at the bottom of the grooved pedal.

[0013] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0014] 1. In the closed state, since the main ladder and the auxiliary ladder are fixed to the fracturing vehicle body by connecting the base, they occupy less space. Due to the downward force of gravity, after opening the rotating plunger on the side, the auxiliary ladder can be quickly rotated to the ground under its own gravity with appropriate force, thus greatly reducing the placement time.

[0015] 2. Since a wedge-shaped anti-collision pad is set between the auxiliary ladder and the fracturing vehicle body, it can not only effectively protect the vehicle paint and avoid bumps, but also play a buffering role when the operator goes up and down. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] See also Figure 1-Figure 4 The utility model provides a fracturing truck ladder assembly, including a fracturing truck body, a main ladder 1 and an auxiliary ladder 2. The compartment of the fracturing truck body is fixedly provided with a connecting base 4 connecting the main ladder 1 and the auxiliary ladder 2; a spare tire platform is provided on the fracturing truck body, the upper end of the main ladder 1 is hinged to the spare tire platform through a connecting ear 14, and the lower end is hinged to the connecting base 4; the auxiliary ladder 2 is located on one side of the main ladder 1, one end of the auxiliary ladder 2 is hinged to the connecting base 4, and the other end is in contact with the ground when the auxiliary ladder 2 is in an open state; a limiting device is also provided on the main ladder 1, and the limiting device is used to keep the auxiliary ladder 2 in a vertical closed state and fixed. The fracturing truck is a special vehicle, which is generally purchased directly, and a relatively large spare tire platform is provided on the top (not shown in the figure). See. Figure 4 Referring to the use state diagram, the upper end of the main ladder 1 is hinged and fixed to the fracturing vehicle body through the connecting ear 14, and the bottom of the auxiliary ladder 2 is almost against the ground. The connecting base 4 between the main ladder 1 and the auxiliary ladder 2 is fixedly connected to the carriage of the fracturing vehicle body. At this time, the operator can reach the corresponding position from the ground along the auxiliary climbing tower and the main ladder 1 to realize the maintenance or operation of the equipment.

[0023] The limiting device of the utility model is a knob plunger 3, and the auxiliary ladder 2 is fixed with a limiting plate 31 adapted to the knob plunger 3. In a static state, the main ladder 1 and the auxiliary ladder 2 are both installed vertically upward and fixed by the limiting device. The limiting device in the utility model is a knob plunger 3. When the knob plunger 3 is working, it ensures the rise or fall of the plunger by rotating a certain angle. When the plunger rises, the limiting plate 31 is engaged to limit the position of the auxiliary ladder 2. When the auxiliary ladder 2 needs to be used, the knob plunger 3 is rotated again, the plunger falls, and after the limiting plate 31 is released from the limit, the auxiliary ladder 2 can rotate around the rotating axis below.

[0024] The auxiliary ladder 2 of the utility model is also fixed with an anti-collision pad 21, which is close to one side of the fracturing vehicle body. The auxiliary ladder 2 is generally made of metal, and a direct collision will make a loud noise, and it is easy to cause bumps and scratches on the paint surface. Therefore, the anti-collision pad 21 can play a good protective role. The anti-collision pad 21 is generally a wedge-shaped one that is wide at the top and narrow at the bottom, directly contacts the fracturing vehicle body, and is generally made of rubber.

[0025] The main ladder 1 and the auxiliary ladder 2 of the utility model are welded with a plurality of grooved pedals 11 in the middle, and a plurality of rectangular teeth 12 are arranged on the top of each grooved pedal 11. The working environment of the fracturing truck is generally bad, and there will be a lot of water. The grooved pedals 11 cooperate with the rectangular teeth 12 to play a good anti-slip role. Even if there is a lot of water, it will flow out through the drainage holes 13.

[0026] 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.
