Description

Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a grouting device for bridge construction. Background Art

[0002] In modern bridge construction, grouting machines are often needed to pour cement and concrete, which can improve the efficiency of road and bridge construction.

[0003] Chinese Utility Model Publication No.: CN214194171U includes a support plate, a first rotating shaft, and a screw. Four first square rods, a second square rod, and a handle are fixedly connected to the upper surface of the support plate, and a ball bearing is embedded in the upper surface of the support plate. A stirring chamber is fixedly connected between the four first square rods. The lower surface of the stirring chamber is connected to and fixed with a discharge pipe with a bottom seal. The discharge pipe is slidably sleeved on the outer side of the first rotating shaft. A spiral stirring blade and a square plate are fixedly connected to the outer side of the first rotating shaft. The outer side of the discharge pipe is connected to and fixedly connected to a square pipe. The lower end of the first rotating shaft is fixedly connected to a first conical tooth. The lower surface of the square plate is fixedly connected to a connecting block. The utility model solves the problem of difficulty in avoiding discharge pipe blockage by cooperating with the first motor, the first rotating shaft, the eccentric wheel, and the spring.

[0004] The applicant found that this patent had some shortcomings in use: by turning the crank to rotate the screw, the third rod was driven to move, and the L-shaped tube was pushed out to make grouting on the outside of the bridge safer. However, the transmission method of the screw and the third rod required the staff to turn the crank several times to extend the L-shaped tube, which was not fast enough and the staff's hands were easily sore.

[0005] Therefore, the utility model designs a grouting device for bridge construction to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a grouting device for bridge construction to solve the problems raised in the above background technology.

[0007] The top of described sliding panel also is provided with an inserting rod, and the bottom of described sliding panel also is provided with an inserting rod.

[0008] Preferably, the fine-tuning component includes a top groove, which is opened at the top of the slider, and a screw rod is rotatably installed in the top groove. The outer wall of the screw rod is slidably installed with a mounting block through a thread, and the top of the mounting block and the bottom of the grouting pipe are fixedly installed. When the trolley moves to the side of the grouting position and there is a deviation between the grouting pipe and the grouting position, there is no need to move the trolley to adjust the position of the grouting pipe. The screw rod can be rotated to move the mounting block to fine-tune the position of the grouting pipe and make the grouting more accurate.

[0009] Preferably, rollers are installed at the four corners of the bottom of the slider, and the rollers are connected to the cart in a rolling manner. When the slider is pushed to move, the rollers roll on the top of the cart, which can reduce the friction of the slider movement and save more effort.

[0010] Preferably, a guide rod fixedly mounted on the trolley is provided in the square groove, and the guide rod and the slider are slidably mounted below the middle thereof, so that the guide rod can limit the slider.

[0011] Preferably, a handle is installed at one end of the screw rod, and the handle makes it convenient for workers to rotate the screw rod.

[0012] Preferably, a rubber sleeve is provided on the upper portion of the L-shaped rod, and the rubber sleeve can improve the comfort of the staff in holding the L-shaped rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. When grouting is required on the outer side of the bridge, the two L-shaped rods can be held in both directions and brought close to each other. The L-shaped rods drive the limit pin to leave the limit hole and enter the through hole and squeeze the spring. Then the staff directly pushes the slider to move to the other end of the square groove, releases the L-shaped rod, and the limit pin can be inserted into the limit hole through the restoring force of the spring. The slider is fixed to extend the grouting pipe, which is faster and reduces the soreness of the staff's hands. BRIEF DESCRIPTION OF THE DRAWINGS
