Description

Technical Field

[0001] The utility model relates to the technical field of material placing machines, in particular to an adjustable fixing device for a material placing machine discharge pipe. Background Art

[0002] During the construction process, concrete is first transported to the concrete placing machine through a pump truck and pipelines. The concrete placing machine then adjusts the angle of its swing arm and boom to adjust the pouring port of the discharge pipe to the area where pouring is required. During pouring, the pouring port of the discharge pipe is manually adjusted so that the concrete flowing out of the discharge pipe can accurately fall to the pouring point. Due to the large pouring area and the weight of the discharge pipe itself, construction workers need to hold the discharge pipe for a long time to maintain its angle, which results in a lot of physical exertion for the construction workers. Utility Model Content

[0003] The problem to be solved by the utility model is to provide an adjustable fixing device for a discharging pipe of a concrete placing machine, which can conveniently adjust and fix the pouring angle of the discharging pipe of the concrete placing machine, thereby reducing the physical exertion of construction workers. The technical solution adopted is as follows:

[0004] An adjustable fixing device for a material placing machine's discharge pipe, characterized in that it includes a support, a universal movable joint, a locking mechanism for locking or unlocking the universal movable joint, and a swing arm for fixing the discharge pipe; the support is used to be fixedly installed at the end of the boom of the material placing machine, the universal movable joint is arranged on the support, the swing arm is arranged vertically, and the upper end of the swing arm is connected and cooperated with the universal movable joint.

[0005] A support is provided at the end of the boom of the concrete placing machine for providing a universal movable joint, and the universal movable joint is locked or unlocked by a locking mechanism. Since the upper end of the swing arm is connected and matched with the universal movable joint, when the universal movable joint is locked and fixed by the locking mechanism, the swing arm cannot rotate in the horizontal plane, so that the discharge pipe maintains a fixed pouring angle for pouring operations, and there is no need for construction workers to hold it by hand for a long time, thereby reducing the physical exertion of construction workers; when the pouring angle of the discharge pipe needs to be adjusted, the locking mechanism is unlocked, the universal movable joint can move, and the swing arm is driven to move accordingly, so that the swing arm can rotate in the horizontal plane, and the construction workers can manually adjust the pouring angle of the discharge pipe at this time. After the adjustment is completed, the locking mechanism re-locks and fixes the universal movable joint, and the pouring angle of the discharge pipe is re-fixed.

[0006] As a preferred embodiment of the utility model, the universal movable joint includes a accommodating box, a universal ball, a pressure block and a tension spring, and the accommodating box is provided with a limit sliding cavity and an accommodating cavity which are connected up and down; the universal ball can be horizontally rotatably placed in the accommodating cavity, the universal ball is fixedly connected to the upper end of the swing rod, and the lower surface of the accommodating box is provided with a through hole for the swing rod to pass through; the pressure block can be slidably arranged in the limit sliding cavity up and down, the upper end of the tension spring is connected to the top surface of the limit sliding cavity, and the lower end of the tension spring is connected to the upper surface of the pressure block; the length of the tension spring is less than the height of the limit sliding cavity; the locking mechanism is used to drive the pressure block to slide downward in the limit sliding cavity, so that the lower surface of the pressure block presses the upper surface of the universal ball.

[0007] The universal movable joint adopts a structure in which a pressure block drives a tension spring to extend and retract and slide up and down in a limited sliding cavity, so that the pressure block presses or loosens the universal ball. The locking mechanism is used to drive the pressure block to slide up and down in the limited sliding cavity, so that the lower surface of the pressure block contacts and cooperates with the universal ball or leaves the universal ball: when the locking mechanism drives the pressure block to slide downward in the limited sliding cavity, so that the lower surface of the pressure block presses the upper surface of the universal ball, the tension spring is stretched, and the pressure block and the accommodating cavity clamp and limit the universal ball, so that the universal ball cannot rotate, and then the swing arm cannot rotate in the horizontal plane, thereby fixing the casting angle of the discharge pipe; when the locking mechanism is unlocked and the pressure block is released, the tension spring is reset due to its own elastic force, and pulls the pressure block up and away from the universal ball, so that the universal ball can rotate, thereby adjusting the casting angle of the discharge pipe.

[0008] As a further preferred solution of the utility model, the cavity wall of the accommodating cavity is a curved surface matching the universal ball, and the lower surface of the pressing block is provided with a curved surface matching the universal ball. When the pressing block is pressed down to contact the universal ball, the pressing block and the accommodating cavity completely surround the universal ball, further limiting and fixing the universal ball.

[0009] As a preferred solution of the utility model, at least two connecting sleeves are provided on the swing rod, each of which is arranged on the swing rod in the up-down direction and is sleeved with the discharge pipe; an operating handle is provided on the lowest connecting sleeve. The discharge pipe is fixed on the swing rod through the connecting sleeve, and an operating handle is provided on the lowest connecting sleeve, so that the construction personnel can manually adjust the pouring angle of the discharge pipe by holding the operating handle.

[0011] As a further preferred embodiment of the utility model, the locking mechanism includes a brake handle, a brake wire and a positioning sleeve; the accommodating box is provided with two opposite vertical guide holes, which are connected to the limit sliding cavity; the lower end of the brake wire is connected with the brake handle, and the upper part of the brake wire is provided with two downward pressure points, which correspond to the two guide holes respectively, and the downward pressure points extend from the guide holes into the limit sliding groove and are connected to the upper surface of the pressure block; the positioning sleeve is arranged on the connecting rocker, and the middle part of the brake wire is connected with the positioning sleeve. The locking mechanism adopts the brake structure in the prior art. When the brake handle is held, the two downward pressure points on the upper part of the brake wire press the pressure block and move the pressure block downward, so that the pressure block presses the universal ball; when the brake handle is released, the downward pressure points release the pressure block, and the pressure block rises and leaves the universal ball under the elastic force of the tension spring itself.

[0012] The positioning sleeve is used to fix the brake wire to prevent the brake wire from swinging.

[0013] Of course, the locking mechanism may also adopt other structures in the prior art, as long as the pressing block can press down the universal ball.

[0014] Compared with the prior art, the utility model has the following advantages:
