Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete pumping, and more specifically, to concrete pumping equipment. Background Art
[0002] Concrete pump, also known as concrete pump, is a machine that uses pressure to continuously transport concrete along a pipeline. It consists of a pump body and a delivery pipe. It is mainly used in building construction, bridge and tunnel construction. The traditional way of fixing the pumping pipeline is to pad the pipeline with tires and square timber, but the effect is poor and the steel bar displacement deviation is relatively serious.
[0003] The utility model with announcement number CN213392541U discloses a concrete pumping device. Since the device is placed on a pouring formwork during concrete pouring, and the surface of the formwork is relatively smooth, vibration will be generated during the concrete pumping process, thereby causing vibration of the device. Installing anti-slip components can effectively prevent the displacement of the device due to vibration, and also prevent the device from hitting nearby steel bars and causing dislocation of the steel bars.
[0004] When the above concrete pumping device is in use, the concrete pumping device body is fixedly connected to the body bracket, and is directly fixedly connected to the height-adjustable support legs and wheels. However, when supporting the concrete pumping device body, the heights of the four support legs need to be adjusted in sequence, which is cumbersome to operate and greatly increases the labor intensity of the staff. Utility Model Content
[0005] In order to overcome the above defects of the prior art, the utility model provides a concrete pumping equipment, aiming to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete pumping equipment, including a mounting frame, a concrete pump body is fixedly installed on one side of the interior of the mounting frame, the input end of the concrete pump body is fixedly connected to a feed pipe, and the output end of the concrete pump body is fixedly connected to a discharge pipe, universal wheels are fixedly installed at the four corners of the bottom end of the mounting frame, a cross plate is fixedly connected to the interior of the mounting frame and at a position located at the bottom of the concrete pump body, a support assembly is provided at the bottom of the cross plate, and the support assembly includes a screw rod, three sleeves, a connecting plate, two sliding rods and four columns.
[0007] Furthermore, the top end of the screw rod is movably connected to the cross plate through a bearing, the top ends of the two sliding rods are fixedly connected to the cross plate, and the bottom ends of the screw rod and the two sliding rods pass through three sleeves respectively, the bottom ends of the three sleeves pass through the mounting frame and are fixedly connected to the connecting plate, and the top ends of the four columns are fixedly connected to the connecting plate.
[0008] Furthermore, a handle is movably provided at the bottom of the horizontal plate, and the handle is fixedly sleeved on the screw rod.
[0009] It can be seen that in the above technical solution, it is convenient to drive the screw rod to rotate.
[0010] Furthermore, the top end of the feed pipe is fixedly connected to a feed hopper, and a support frame is fixedly installed on the feed hopper.
[0011] Furthermore, a stirring assembly is provided on the support frame, and the stirring assembly includes a motor, a rotating shaft and a plurality of stirring blades.
[0012] Furthermore, the motor is fixedly mounted on the top of the support frame, the top of the rotating shaft is fixedly connected to the end of the motor output shaft, and the plurality of stirring blades are fixedly sleeved on the rotating shaft.
[0013] Furthermore, a control valve is fixedly installed on the feed pipe.
[0014] It can be seen that in the above technical solution, the outflow speed of the concrete in the feed hopper can be controlled by the control valve.
[0015] Technical effects and advantages of the utility model:
[0016] 1. The utility model drives the screw to rotate by rotating the handle. Since one sleeve is threadedly connected to the screw, and the other two sleeves and two slide bars cooperate to limit the rotation of the connecting plate, the screw can drive the connecting plate to move downward, and then drive the four columns to move downward, so that the four columns are in contact with the ground, and the mounting frame is limited, thereby improving the stability of the mounting frame. Similarly, the handle is reversed to move the four columns upward, which is simple to operate and effectively reduces the labor intensity of the staff;
[0017] 2. The utility model pours concrete into the feed hopper, supports the motor with a support frame, starts the motor, and drives the rotating shaft to rotate, thereby driving a plurality of stirring blades to rotate. The plurality of stirring blades stir the concrete in the feed hopper to prevent the concrete from settling. The concrete pump body is started, and the concrete pump body extracts the concrete in the feed hopper through the feed pipe and discharges it through the discharge pipe. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
