Embodiment 1

[0020] The tapered sleeve locking type steel bar connection joint mentioned in the present invention includes a locking plate group 1 and a tapered sleeve 2. The locking plate group 1 is in the shape of a shuttle as a whole, and there are locking tooth grooves 1-1 inside it. There is a pair of taper sleeves 2, the inner cavity of which is in the shape of a vertebra, and the pair of taper sleeves 2 are symmetrically set on the locking plate group 1. The inside of the locking plate group 1 is also provided with a boss 1-2, and the boss 1- 2 is arranged at the middle position of the inner surface of the lock plate group 1, and plays a role of positioning the steel bar 3 to be connected.

[0021] refer to figure 1 — Figure 5 , the hydraulic installation tool for installing the taper sleeve locking type steel bar connection joint in this embodiment includes a pull rod 4, a hydraulic control mechanism, and a pressure head 5, and the pull rod 4 is fixedly connected with the hydraul...

Embodiment 2

[0025] refer to image 3 — Figure 7 The difference between this embodiment and Embodiment 1 is that the hydraulic control mechanism is a hydraulic cylinder 9 provided with two hydraulic oil inlets and outlets 9-1, 9-2, and the pull rod 4 is fixedly connected to the hydraulic cylinder 9 one end of the piston 10. The hydraulic oil inlet and outlet 9-1, 9-2 can be connected with a manual or electric hydraulic pump, and a reversing valve needs to be installed between the hydraulic pump and the hydraulic oil inlet and outlet 9-1, 9-2 to realize hydraulic oil. output and oil return.

[0026] Using the hydraulic installation tool for installing the tapered sleeve locking type steel bar connection joint described in this embodiment to install the tapered sleeve locking type steel bar connection joint as described in Example 1 and the method for connecting the steel bars are as follows: (1) put two The taper sleeves 2 are respectively set on the ends of the two steel bars 3 to be c...

Abstract

The invention discloses a hydraulic mounting tool for mounting a taper sleeve locking type reinforcing steel bar connecting joint. The hydraulic mounting tool comprises a pull rod, a hydraulic control mechanism and a pair of pressing heads, wherein the pull rod is fixedly connected with the hydraulic control mechanism, and a pair of the pressing heads are fixedly connected on the hydraulic control mechanism and the pull rod respectively. According to the hydraulic mounting tool, a distance between the two pressing heads can be controlled by hydraulic pressure of the hydraulic control mechanism, so that the taper sleeve locking type reinforcing steel bar connecting joint can connect reinforcing steel bars to be connected, the structure is simple, the operation is convenient, the tension strength is high, the labor of operators can be greatly alleviated, the mounting efficiency is improved, and the hydraulic mounting tool can mount firmly without loosing phenomenon.

Description

technical field [0001] The invention belongs to the technical field of steel bar connection, and in particular relates to a hydraulic installation tool for installing a taper sleeve locking type steel bar connection joint. Background technique [0002] The Chinese invention patent CN201310743064.6 and the Chinese utility model patent CN201320877655.8 applied by our company both record a tapered sleeve locking type steel bar connection joint and its installation tool. This installation tool drives the worm wheel and the screw through the rotating worm Rotate, and then through the transmission action of the screw nut pair, the pressure heads produce axial extrusion movement and approach each other, and apply extrusion force to the end of the taper sleeve to squeeze, so as to achieve the purpose of shortening the distance between the two taper sleeves. The structure is relatively complicated, and the pulling force generated is slightly low, which is too labor-intensive for the ...
