Embodiment 1

[0056] This embodiment provides a rubber cartridge type hydraulic chuck slip installation tool, such as Figure 3 to Figure 8 As shown, it includes: a support seat 3, the support seat 3 includes a flat plate 31 and a support leg 32; it also includes a tightening mechanism 1 and a pressing mechanism 2, the tightening mechanism 1 is used to tighten the slips along the radial direction of the slips, The pressing mechanism 2 is used to press down the rubber cartridge until it is completely fitted on the outside of the slip; wherein, the tightening mechanism 1 is adjacent to the pressing mechanism 2 and is installed on the supporting base 3 . The rubber cartridge type hydraulic chuck slip installation tool of the present invention is simple in structure, easy to operate, and high in installation efficiency. The tightening mechanism 1 enables the three pieces of slips to overcome the pressure of the return spring and tighten along the radial direction of the slips so that the rubber ...

Embodiment 2

[0071] This embodiment provides a rubber cartridge type hydraulic chuck slip installation method, the installation method is based on the above installation tool, the steps are as follows:

[0072] Step 1: Install slips: such as Figure 9 As shown, the three pieces of slips 43 are respectively placed on the guide plate 12, and the guide block 45 of the slips 43 is embedded in the slide rail 121 of the guide plate 12; hole, and ensure that each return spring 44 is worn in the corresponding cylindrical counterbore of two adjacent slips 43;

[0073] Step 2: Tighten the slips: such as Figure 10 As shown, high-pressure hydraulic oil is introduced into the rod cavity of the tightening cylinder 132, and the piston rod of the tightening cylinder 132 is driven to recover, driving the push-pull plate 131 to move downward, and the push-pull plate 131 drives the three retractable cylinders through three connecting rods 134. The pressing plate 11 moves toward the center of the guide pla...

Abstract

The invention discloses a rubber cylinder hydraulic chuck and slip mounting tool and mounting method. The mounting tool comprises a supporting seat and further comprises a tightening mechanism and a lower pressing mechanism, the tightening mechanism is adjacent to the lower pressing mechanism, the tightening mechanism and the lower pressing mechanism are mounted on the supporting seat, the tightening mechanism is used for tightening slip in the radial direction of the slip, and the lower pressing mechanism is used for pressing a rubber cylinder downwards to be completely mounted at the exterior of the slip in a sleeving mode; and the tightening mechanism comprises a plurality of tightening pressing plates distributed along the circumference, a guide plate with a plurality of slide rails and a first driving unit used for controlling the tightening pressing plates to slide along the slide rails, the tightening pressing plates is slidably mounted on the slide rails, the guide plate penetrates through and is fixed on a flat plate of the supporting seat, the first driving unit is connected to the lower ends of the tightening pressing plates and is fixedly mounted below the guiding plate, the lower pressing mechanism comprises a lower pressing swing arm and a second driving unit used for driving the lower pressing swing arm to move vertically, and the second driving unit is connectedto the lower pressing swing arm and perpendicularly fixed on the flat plate of the supporting seat. The mounting tool is simple in structure, convenient to operate and high in mounting efficiency.

Description

technical field [0001] The invention relates to a chuck slip installation tool and an installation method, in particular to a rubber cylinder type hydraulic chuck slip installation tool and an installation method. Background technique [0002] The hydraulic chuck is the key component of the full hydraulic tunnel drilling rig. When the drilling rig trips and unscrews the drill pipe, it depends on the powerful clamping of the drill pipe by the hydraulic chuck. Rubber cartridge hydraulic chucks are widely used in full hydraulic tunnel drilling rigs due to their large clamping force and quick response. During the installation process of the hydraulic chuck slips, the return spring needs to be compressed to a certain size and then loaded into the rubber cartridge that has been fitted with the chuck body. Due to the large number and high stiffness of the return springs, the current method of manually extruding the slips has disadvantages such as low installation efficiency and hi...
