Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1 and 3, the utility model discloses a hydraulic pressure track slide plate pin puller is the device of extracting the pin on the track slide plate, including support frame 1 and the hydraulic transmission portion 2 of roof in support frame 1 fixed connection, the transmission of the output of hydraulic transmission portion 2 is connected with output rod 3. The hydraulic transmission part 2 can drive the output rod 3 to vertically move when working, and the hydraulic transmission part 2 is connected with an external hydraulic station.

Referring to fig. 1, the pin is located below the output rod 3 and the pin is located within the track slide plate. The top of the pin is welded with a fixed cover 4, the fixed cover 4 is arranged in a T shape, and the diameter of the cross section of the fixed cover 4 is larger than that of the cross section of the pin. 3 bottom fixedly connected with bottom plates 5 of output rod, 5 both sides of bottom plate all rotate and are connected with supporting

rod

6, and 6 bottom fixedly connected with grip blocks 7 of supporting rod. The outer peripheral surface of the output rod 3 is sleeved with a circular ring 8, and an adjusting assembly 9 is arranged between the circular ring 8 and the output rod 3.

Referring to fig. 1 and 2, the adjustment assembly 9 includes two sliding grooves 91, and the sliding grooves 91 are formed on the outer peripheral surface of the output rod 3. A lead screw 92 is vertically and rotatably connected to the slide groove 91. The inner peripheral surface of the ring 8 is fixedly connected with two limiting blocks 93 corresponding to the sliding grooves 91, and the limiting blocks 93 are connected in the corresponding sliding grooves 91 in a sliding manner, so that the ring 8 can only move vertically. The lead screw 92 is in threaded connection with the limiting block 93, and the lead screw 92 rotates to drive the limiting block 93 to move vertically. A driving portion 94 is disposed above the limiting block 93.

Referring to fig. 2, the driving part 94 includes two worm wheels 941, and the worm wheels 941 are fixedly coupled to outer circumferential surfaces of the corresponding lead screws 92. A worm 942 is arranged on one side of the output rod 3, and the worm 942 is meshed with two worm wheels 941. The worm 942 rotates to drive the two worm wheels 941 to rotate, the worm wheels 941 rotate to drive the lead screws 92 to rotate, and when the two lead screws 92 rotate, the two limit blocks 93 move in the same direction. One end of the worm 942 extends to the outside of the output rod 3, which facilitates the operator to rotate the worm 942.

Referring to fig. 1, two connecting rods 10 are hinged to the outer peripheral surface of the ring 8, and one end of each connecting rod 10, which is far away from the ring 8, is hinged to the corresponding clamping rod 6. The vertical motion of ring 8 drives connecting rod 10 motion, and connecting rod 10 drives supporting rod 6 motion, and supporting rod 6 drives grip block 7 motion. When the stopper 93 is in contact with the bottom wall of the corresponding sliding groove 91, the holding block 7 is leveled with the bottom surface of the fixed cover 4.

Referring to fig. 1, four thread grooves are formed in the bottom of the support frame 1, and support legs 11 are connected to the thread grooves in an internal thread mode. The height of stabilizer blade 11 can be adjusted to rotation stabilizer blade 11, makes four stabilizer blades 11 all contact with the track slide chair board, prevents that this device from placing the condition emergence of empting on the plane of slope, and can prevent when stopper 93 with correspond the contact of bottom wall in the sliding tray 91, grip block 7 is located fixed lid 4 top, the condition emergence of unable fixed lid 4 of contact.

The implementation principle of the above embodiment is as follows:

at first place the position that corresponds the pin at track slide chair top with this device, rotate stabilizer blade 11, make four stabilizer blades 11 all contact with track slide chair top, rotate worm 942 after that, worm 942 drives worm wheel 941 and rotates, and worm wheel 941 rotates and drives lead screw 92 and rotate, and when two lead screw 92 rotated, two stopper 93 moved downwards in step to make ring 8 downstream. The movement of the circular ring 8 drives the connecting rod 10 to move, the connecting rod 10 drives the clamping rod 6 to move, and the clamping rod 6 drives the clamping block 7 to move. Until the stop block 93 contacts with the bottom wall of the corresponding sliding groove 91, the clamping block 7 is horizontal to the bottom surface of the fixed cover 4, and the clamping block 7 is positioned below the fixed cover 4.

Then, the hydraulic transmission part 2 is started to drive the output rod 3 and the bottom plate 5 to move upwards, the bottom plate 5 drives the clamping block 7 to move upwards to contact the fixed cover 4, then the clamping block 7 continues to move upwards to drive the pin to move, and therefore the pin can be stably pulled out.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
