Abstract
The utility model relates to a mining equipment appurtenance specifically is a hydraulic wrench, which comprises a housin, casing one end sets firmly the pneumatic cylinder, is different with prior art: the hydraulic cylinder is provided with a first hydraulic oil inlet and a second hydraulic oil inlet, and the first hydraulic oil inlet and the second hydraulic oil inlet can be connected with a hydraulic system of the mining machinery; the hydraulic cylinder is characterized in that a rack and a shaft head are arranged in the shell in a sliding mode, a gear is fixedly arranged on the shaft head, the rack is meshed with the gear, the rack is fixedly connected with a cylinder rod of the hydraulic cylinder, and one end, penetrating out of the shell, of the shaft head can be inserted into hexagonal sleeves of different specifications. Compared with the prior art, the utility model discloses need not dispose independent hydraulic system alone, can directly use the hydraulic system of mining machinery itself, it is nimble more convenient to use. The inner structure is also different, and current hydraulic wrench is the ratchet cooperation, the utility model discloses a rack and pinion cooperation, more simple and practical, anti the making.
Description
Technical Field
The utility model relates to a mining equipment appurtenance specifically is a hydraulic pressure spanner.
Technical Field
Mining machinery is like excavator, loader in the maintenance process, and manual tool is like loose plate, fork board inefficiency, hard, sometimes can not be for doing all to do all, consequently generally can use hydraulic wrench, and current hydraulic wrench need cooperate and use dedicated hydraulic pump, and dedicated hydraulic pump is opened during the use, can rotate through the motor after the start work and produce pressure, then orders about hydraulic oil and transmits the piston rod to the spanner through hydraulic pressure oil pipe, and then the piston rod passes through the ratchet and drives the drive shaft and screw up or not hard up the operation. The piston rod and the transmission part are combined together to form a kinematic pair, the distance between the center of the oil cylinder and the center of the transmission part is the large arm force of the spanner, and the theoretical value of the output torque is calculated by multiplying the output force of the oil cylinder by the length of the arm force according to the lever principle. However, since the hydraulic wrench needs a dedicated hydraulic pump, the wrench cannot be used without power supply during field operation.
Disclosure of Invention
For overcoming the not enough of current hydraulic wrench, the utility model discloses a novel hydraulic wrench, which comprises a housin, casing one end sets firmly the pneumatic cylinder, and is different with prior art: the hydraulic cylinder is provided with a first hydraulic oil inlet and a second hydraulic oil inlet, and the first hydraulic oil inlet and the second hydraulic oil inlet can be connected with a hydraulic system of the mining machinery; the hydraulic cylinder is characterized in that a rack and a shaft head are arranged in the shell in a sliding mode, a gear is fixedly arranged on the shaft head, the rack is meshed with the gear, the rack is fixedly connected with a cylinder rod of the hydraulic cylinder, and one end, penetrating out of the shell, of the shaft head can be inserted into hexagonal sleeves of different specifications.
Compared with the prior art, the utility model discloses need not dispose independent hydraulic system alone, can directly use the hydraulic system of mining machinery itself, it is nimble more convenient to use. The inner structure is also different, and current hydraulic wrench is the ratchet cooperation, the utility model discloses a rack and pinion cooperation, more simple and practical, anti the making.
The shaft head is connected with the shell through a shaft, the shaft head is connected with the shell through a shaft sleeve, and the shaft head is connected with the shell through a shaft sleeve. Thus, the assembly is convenient, and the lubricating grease in the gland shell can be conveniently replaced in time.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view at a-a in fig. 1.
Detailed Description
The hydraulic wrench shown in fig. 1 and 2 comprises a housing 1, wherein a hydraulic cylinder 5 is fixedly arranged at one end of the housing 1, the hydraulic cylinder 5 is provided with a first hydraulic oil inlet and outlet 6 and a second hydraulic oil inlet and outlet 7, and the first hydraulic oil inlet and outlet 6 and the second hydraulic oil inlet and outlet 7 can be connected with a hydraulic system of mining machinery; the novel hydraulic cylinder is characterized in that a rack 2 and a shaft head 3 are arranged in the shell 1 in a sliding mode, a gear 8 is fixedly arranged on the shaft head 3, the rack 2 is meshed with the gear 8, the rack 2 is fixedly connected with a cylinder rod of the hydraulic cylinder 5, and the shaft head 3 penetrates out of one end of the shell 1 and can be plugged with hexagonal sleeves 9 of different specifications. The novel bearing shell is characterized by further comprising a gland 4, wherein the gland 4 is fixedly arranged on the shell 1 through a plurality of screws 10, and one end of the shaft head 3 is connected with the gland 4 in a switching mode.
The hydraulic system of the mining machine such as a shovel can be directly used without separately configuring an independent hydraulic system. The internal structure is also different, and current hydraulic wrench is the ratchet cooperation, and this patent is rack and pinion cooperation. Compared with the prior art, the utility model discloses change inner structure's structure, the structure is simpler practical. The hydraulic system is not needed to be configured independently, and the use is more flexible and convenient.
