Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present invention.

With the gradual formalization of modification, the concept of integrated modification is not only an assembly problem between frame beams, but also a reasonable arrangement that takes into account space, performance, maintenance and other dimensions in concept. Embodiments of the present invention provide an integrated modified truck-mounted crane vehicle, which can solve the problems in related technologies of reduced quality of the entire vehicle, increased modification costs, low transmission efficiency, and high operating fuel consumption.

Referring to Figure 1, an integrated modified truck-mounted crane vehicle is provided in an embodiment of the present invention, which may include: a frame assembly 1, to which a power take-off 4 is fixed; an oil pump bracket 3, which is fixed to the On the frame assembly 1, an oil pump 5 is installed on the oil pump bracket 3. The oil pump 5 is connected to the power take-off 4 through a transmission mechanism 2. The transmission mechanism 2 has a preset length and is connected to the power take-off 4. There is a preset angle between the oil pump 5 and the power take-off 4; the power take-off 4, the oil pump bracket 3 and the transmission mechanism 2 are all located inside the frame assembly 1.

In the related technology, the oil pump is installed at the bottom of the car without fixing its position. At present, the modification factory cannot identify the impact of the transmission loss caused by modification. Usually, the matching design of the power take-off and the transmission system is unreasonable, and the angle is too high. Large, it will affect the performance of the vehicle. Transmission jitter caused by excessive angle will occur, the transmission efficiency will be low, and the operating fuel consumption will be high. The working energy efficiency of the power take-off is a fixed value. If the transmission loss is small, the power take-off with a small speed ratio can be matched to achieve the target torque. On the contrary, if the loss is large, a large speed ratio must be matched to achieve the target torque, resulting in increased costs and loss of performance. In this embodiment, by arranging the positions of the transmission mechanism 2 and the oil pump 5, sufficient external modification space is reserved for installing the fuel tank and other accessories, so that the modification positions are unified, and there is no need to drill into the bottom of the vehicle for assembly. It can be directly hoisted, which improves the convenience of modification and solves the problems of chaotic modification, inconsistent parts, and inconvenient modification; through this arrangement, the chassis and accessories such as oil pumps can be integrated, and the modification factory only assembles the crane and cargo box. That is, the modification cycle is shortened, human resources are saved, operating efficiency is improved, and the problems of long modification cycle and high labor cost are solved; by designing the angle and length of the transmission mechanism 2, the problems of jitter and low efficiency are effectively solved, thereby reducing losses. The performance is improved from an angle, which solves the problem of kinetic energy loss caused by the layout and improves the performance of the entire vehicle.

Referring to Figure 1, preferably, the angle between the transmission mechanism 2 and the frame assembly 1 is 2-3°, and the angle between the transmission mechanism 2 and the power take-off 4 is 0-0.5°.

In this embodiment, the transmission mechanism 2 connects the power take-off 4 and the oil pump 5, and drives the oil pump 5 to work through the work of the power take-off 4. During operation, the transmission mechanism 2 has a necessary angle with the power take-off 4 and the oil pump 5, resulting in rotation transmission. The necessary energy loss is usually designed to accept 5% loss. Therefore, the length of the transmission shaft designed in the present invention is 700mm, the lateral angle is 3°, the angle between the longitudinal power take-off 4 and the frame assembly 1 is 3°, and the transmission shaft The angle between the frame and the frame is 2.5°, and the angle between the power take-off 4 and the transmission shaft is 0.5°. Under these conditions, the results were obtained through experimental tests: the transmission efficiency is 96%, which meets the settings, and the jitter frequency of the entire mechanism under this length is equal to The frequency peaks of the engine and frame are shifted, and the vibration of the entire vehicle is minimally affected. This arrangement method effectively improves efficiency.

Referring to FIG. 2 , in some embodiments, a plurality of the formed pipes 7 are arranged side by side along the length direction of the vehicle on the multi-tube card 6 .

In this embodiment, by arranging a plurality of shaped pipelines 7 side by side and running forward and backward, the pipelines can be seen at a glance during maintenance, which improves the convenience of maintenance.

Referring to FIG. 2 , in some embodiments, the end of the formed pipe 7 is provided with a quick-fit connector 8 . In this embodiment, since there are quick-in connectors 8 on both sides of the molded pipeline 7, only "letter" connectors need to be used for insertion during modification, so that the quick-in connectors 8 can be connected to the chassis and the modified gas line to solve the problem It eliminates the difficulty of checking the pipeline during subsequent maintenance. At the same time, the quick-plug connection is also convenient for disassembly. The steel pipe direction is smooth and beautiful, which meets the design concept of integrated chassis and modification.

Referring to Figure 2, in some embodiments, the transmission mechanism 2 is located between the molded pipeline 7 and the frame assembly 1. In this embodiment, the transmission mechanism 2, the power take-off 4, and the oil pump Bracket 3 and oil pump 5 are assembled on the inside of the frame, which simultaneously releases the external space on the left and right sides of the frame, leaving enough space for modification, which greatly improves the convenience of modification of the entire vehicle. This arrangement is mass-produced by the chassis production line and takes 5 minutes. , and at the same time, it also prevents workers from wasting time on bottom work during modification, and solves the problems of long modification cycle and difficult assembly.

Referring to Figure 2, in some embodiments, symmetrical areas 9 for installing the transmission mechanism 2 are provided between opposite sides of the molded pipe 7 and the frame assembly 1. In this embodiment In the middle, the transmission mechanism 2, power take-off 4, oil pump bracket 3 and oil pump 5 are assembled with the inner left side of the frame assembly 1. According to the needs of the power take-off 4, they can be symmetrically assembled to the symmetrical area 9 on the right inner side of the frame, which improves the Adaptation versatility of this mechanism.

Among them, the power take-off 4 is fixed on the frame assembly 1 through a rubber cushion, which can provide buffering for the power take-off 4 and absorb vibration; the transmission mechanism 2 includes a transmission shaft and a The universal joints at both ends of the transmission shaft, the transmission mechanism 2 are used to output the kinetic energy of the power take-off 4 to the oil pump 5; the oil pump 5 is assembled on the oil pump bracket 3 through bolts.
