Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the drawings:

[0027] Such as figure 1 , 2 As shown in, 3 or 4, the present invention includes a mounting base 1. On the mounting base 1, a variable cylinder 2, a quantitative cylinder 4, and a center bracket 3 are fixed. The top of the piston rods of the variable cylinder 2 and the quantitative cylinder 4 are connected with the center bracket 3 as a fulcrum. , A handle 5 that drives the piston rods of the variable cylinder 2 and the quantitative cylinder 4 to achieve displacement. The end of the piston rod of the variable cylinder 2 is connected to a variable adjustment mechanism 6. The variable adjustment mechanism 6 includes a stroke adjustment head 6 fixed to the end of the piston rod. 2. The stroke adjustment head 6-2 is connected to the pin shaft 17 with the vertical direction guide key, and the pin shaft 17 is hinged to the handle 5. The top of the stroke adjustment head 6-2 is conne...

Abstract

The invention relates to a double-cylinder variable hand-operated grouting pump, particularly to a hand operating device used for double-liquid grouting; a handle which takes a center support as a supporting point and drives piston rods of a variable cylinder and a quantitative cylinder to realize displacement is connected at the top parts of the piston rods of the variable cylinder and the quantitative cylinder, the end part of the piston rod of the variable cylinder is connected with a variable adjusting mechanism, the variable adjusting mechanism comprises a stroke adjusting head which is fixedly connected with the end part of the piston rod, a guide key of the stroke adjusting head along the vertical direction is connected with a pin shaft which is articulated with the handle, an adjusting screw rod which can control the relative stroke between the pin shaft and the stroke adjusting head is connected at the top part of the stroke adjusting head by a screw pair; in the invention, the discharging quantity can be changed during working of the double-cylinder variable hand-operated grouting pump, the variable cylinder can realize the change of discharged liquid volume by adjusting a working stroke of a piston, so as to control and adjust the injection quantity ratio of additives and cement grout, the working stroke of the piston of the variable cylinder is adjusted by the stroke adjusting head, and the structure of the double-cylinder variable hand-operated grouting pump is simple, stable and reliable.

Description

Technical field [0001] The invention relates to a dual-cylinder variable hand pressure grouting pump, in particular to a manual device for dual-liquid grouting. Background technique [0002] Grouting technology is mainly used for tunnel wall lining and underground water control. [0003] Concrete spraying machines are widely used in the lining construction of large cross-section walls in underground projects, shafts, tunnels, culverts, etc., with high mechanization and high construction efficiency. [0004] When the construction work space is small, especially when repairing loopholes and lining defects, a flexible and small-sized grouting device is required; the grouting pump is used for grouting and blocking water in underground engineering, and grouting and blocking water in rock tunnels and concrete walls And foundation grouting reinforcement tools; for underground water control, etc., when the seepage area is small, the seepage pressure is low, or the grouting area is small, ma...
