Abstract

The invention discloses a novel hydraulic lifting appliance. The novel hydraulic lifting appliance comprises a hydraulic lifting rod (1), a hydraulic system (2), an electric control box (4) and a laser range finder (3), wherein the hydraulic lifting rod (1) comprises a cylinder barrel (5), a primary piston rod (6), a secondary piston rod (11), an innermost-stage piston rod (12), an exhaust pipe (13), a sealing assembly, a support ring (25), a shaft limiting key (23), a hole limiting key (22), a long key groove (36) and a guide key (24); a one-way valve opening plunger assembly (28) is arranged in a rear cover (14), and comprises a plunger (28-6), an oil port (28-1), a channel (28-2), a reverse one-way valve (28-3) and a thimble; a one-way sealing assembly (27) is arranged in the secondary piston rod (11), and comprises a sealing plunger (27-3) and a one-way (27-1), and the sealing plunger (27-3) is connected to an exhaust pipe seat (27-2) connected with the exhaust pipe (13). The novel hydraulic lifting appliance is capable of preventing rotation in the total travel and provided with the laser range finder so that self-detection and self-control of the positions of the piston rods are realized, and moreover, the desired heights of the piston rods can be maintained automatically and the lifting order of the piston rods is controllable.

Description

Technical field: [0001] The invention relates to a hydraulic lifting device, in particular to a new type of hydraulic lifting device which is anti-rotation in full stroke and equipped with a laser range finder to realize autonomous detection and control of antenna rising height, automatic maintenance of required height and controllable lifting sequence . Background technique: [0002] With the rapid development of communication technology, 2G, 3G, and 4G networks have emerged and been widely used. At the same time, emergency communication equipment also needs to keep up with the development of communication technology. In this case, the original mechanical and electric lifting equipment cannot meet the status quo, so the hydraulic lifting equipment applied to the double network has been developed accordingly. The existing electric and mechanical lifting equipment cannot meet the following requirements: [0003] 1. The existing lifting equipment can only load one kind o...
