Description

Technical Field

[0001] The utility model relates to the technical field of heavy object transporting, in particular to a transport vehicle which can be lifted and lowered. Background Art

[0002] During the maintenance work of hydropower stations, heavy objects are often involved in transportation. In many cases, the work site is not flat, and heavy objects need to be transferred and carried between different heights, which brings difficulties to the maintenance work. Existing transport vehicles can usually only transport heavy objects on relatively flat ground. When encountering stairs or slopes, it is usually necessary to use a hand winch or a crane for transportation, which is not only time-consuming and labor-intensive, but also has high risks. Based on this, a liftable transport vehicle is designed. The heavy objects can be transported between different heights or on stairs by lifting multiple sets of liftable tire assemblies. During the process, the horizontal state of the transport vehicle can be guaranteed to remain unchanged, so as to reduce the manpower consumption during the transportation process and improve the safety of the operation, solving the problem of time-consuming, labor-intensive and high-risk equipment transportation in the prior art.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0026] The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] In one embodiment of the present application:

[0028] like Figures 1 to 6 As shown, a liftable transport vehicle comprises a transport vehicle body and three sets of liftable tire assemblies, each set of liftable tire assemblies comprises two liftable tires, and the two liftable tires are respectively arranged on the left and right sides of the transport vehicle body.

[0029] A liftable tire includes a hydraulic cylinder 12, a reversing valve 13, a plunger pump 14, a motor 15 and a load-bearing tire 16. The hydraulic cylinder 12 includes a cylinder and a piston rod. Six balance detectors 3 and an information processor 1 are arranged at the bottom of the transport vehicle body. The balance detector 3 is connected to the information processor 1, and the information processor 1 is connected to the motor 15. The motor 15 controls the plunger pump 14 to work. The plunger pump 14 and the reversing valve 13 control the piston rod to move up and down along the cylinder. The load-bearing tire 16 is fixedly connected to the piston rod. The balance detector 3 can measure the balance of the entire transport vehicle. When the transport vehicle tilts, the balance detector 3 detects a signal and sends the signal to the information processor 1. After receiving the signal, the information processor 1 calculates and outputs the data to each motor 15. The motor 15 drives the plunger pump 14 to work, controls the extension and contraction of the piston rod through the reversing valve 13, and drives the load-bearing tire 16 to move up and down, so that the transport vehicle can maintain balance during climbing or going up and down stairs. For example: if the heights measured by each balance detector 3 are consistent, it means that the entire transporter is in a balanced state. If the heights measured by one of the balance detectors 3 are inconsistent with the heights measured by the other balance detectors 3, it means that the entire transporter is in an unbalanced state. At this time, the information processor 1 calculates which balance detector 3 is higher / lower than the height measured by the other balance detectors 3 by a few centimeters. The information processor 1 needs to control the motor 15 at that balance detector 3 to rotate forward / reverse for a certain number of times. The motor 15 drives the plunger pump 14 to start pumping oil, and the reversing valve 13 controls the plunger pump 14 to pump oil forward / reverse, thereby controlling the extension / contraction of the piston rod and driving the load-bearing tire 16 to move down / up.

[0030] A battery 2 is also provided at the bottom of the transport vehicle body. The battery 2 is connected to the information processor 1 and the motor 15 respectively, and the battery 2 provides power for the information processor 1 and the motor 15 .

[0031] The main body of the transport vehicle includes a main body 5, a mobile trolley 10 and a base plate 4. The main body 5 is arranged on the top of the base plate 4 and is fixedly connected to the base plate 4. Two parallel slide grooves 6 are arranged on the main body 5. A pulley 9 is respectively arranged at the four corners of the bottom of the mobile trolley 10. The four pulleys 9 can move forward and backward along the slide grooves 6 to shift the center of gravity of the heavy objects on the mobile trolley 10 when the transport vehicle climbs a slope or goes up stairs to keep the balance of the entire mobile trolley 10.

[0032] A baffle 7 is provided at one end of the two slide grooves 6 to prevent the moving trolley 10 from escaping from the slide grooves 6. An operation panel 8 is provided at the other end of the two slide grooves 6. The operation panel 8 is connected to the motor 15. Instructions can be given through the operation panel 8 to control the up and down movement of the load-bearing tires 16 of each group of liftable tire assemblies.

[0033] A towing handle 11 is provided at the front end of the mobile vehicle 10 .

[0034] Three brackets 19 are respectively arranged on the left and right sides of the bottom plate 4 , six balance detectors 3 are respectively arranged on the top of the six brackets 19 , and six cylinders capable of lifting and lowering tires are respectively fixedly connected to the six brackets 19 .

[0035] Take carrying a heavy object up the stairs as an example. The heavy object is placed on the moving trolley 10. When encountering stairs, the moving trolley 10 is controlled by pulling the handle 11 to move the moving trolley 10 to the rear of the main vehicle body 5 so that the center of gravity of the heavy object is moved to the rear of the vehicle. An instruction is given through the operation panel 8 to drive the motor 15 on the first set of liftable tire assemblies at the front of the transport vehicle to drive the plunger pump 14 to work, and the piston rod is controlled to contract through the reversing valve 13, so that the load-bearing tire 16 rises, and the first set of liftable tire assemblies rises to the upper step. Then, the mobile cart 10 is moved by dragging the handle 11 to the front of the main vehicle body 5, and then an instruction is given through the operation panel 8 to allow the motor 15 on the second set of liftable tire assemblies in the middle of the transporter to drive the plunger pump 14 to work, and the contraction of the piston rod is controlled by the reversing valve 13 to make the load-bearing tire 16 rise, so that the second set of liftable tire assemblies can be raised to the upper step, and the above steps are repeated to achieve the third set of liftable tire assemblies to rise to the upper step, thereby realizing the entire heavy object transportation across the stairs.

[0036] In another embodiment of the present application:

[0037] On the basis of the first embodiment, this embodiment makes an improvement on the liftable tire, and the liftable tire further comprises a shock-absorbing suspension 17, and the shock-absorbing suspension 17 is arranged between the load-bearing tire 16 and the piston rod to reduce the vibration amplitude when going up and down stairs.

[0038] The cylinders of adjacent liftable tires are fixedly connected by railings 18, so that the three cylinders on the left / right side of the transport vehicle can be connected into a whole.
