Description

Technical Field

[0001] This utility model relates to the field of concrete testing benches, and in particular to a multifunctional concrete testing bench. Background Technology

[0002] A concrete test bench is a device suitable for the molding and vibration of various concrete components such as slabs, columns, and beams in laboratories and on-site construction sites.

[0003] However, the current concrete testing platform has some shortcomings. The vibration platform of the concrete testing platform is fixedly equipped with a frame, but the frame is fixed and its height is not adjustable. When it is necessary to produce taller concrete products on the vibration platform, it is impossible due to the height limitation of the frame. In addition, since the frame is higher than the vibration platform, it is not convenient to clean the vibration platform. Utility Model Content

[0004] The main objective of this invention is to provide a multifunctional concrete testing bench that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multifunctional concrete test bench includes a base, springs, and a vibration platform. Springs are provided between the base and the vibration platform and at the four corners. Support frames are fixedly installed on both sides of the vibration platform. A rectangular frame is movably fitted on the surface of the vibration platform. Positioning elements are provided on both sides of the rectangular frame. Gears are movably installed inside the support frame.

[0007] Preferably, positioning grooves are provided on both sides of the rectangular frame near the front and rear, and the number of positioning grooves is four. Sliders are fixedly installed on both sides of the inner side of the rectangular frame near the front and rear bottom, and rubber pads are provided on the inner surface of the rectangular frame.

[0008] Preferably, the vibration platform has longitudinal grooves on both sides and near the front and rear, the slider is embedded in the grooves, and the rectangular frame is movably connected to the vibration platform through the slider.

[0009] Preferably, the support frame has a rectangular groove inside, and a rotating groove is formed inside the support frame above and below the middle of the rectangular groove. A slot is formed on the upper and lower surfaces of the rectangular groove near both sides. A right-angle rod is fixedly installed on the lower surface of the support frame near both ends. The support frame is fixed to the vibration platform by the right-angle rod.

[0010] Preferably, the positioning component includes a pull plate, a pin, a rack, and a retaining strip. The rack is fixedly installed on the inner surfaces of both ends of the pull plate, and the retaining strip is fixedly installed on the upper and lower surfaces of the rack. The pin is fixedly installed on the inner surface of the pull plate near the lower ends.

[0011] Preferably, a rotating rod is fixedly installed on the upper and lower surfaces of the gear, one end of the rotating rod extends into the rotating groove, a stop block is fixedly installed on the surface of one end of the rotating rod, and a torsion spring is sleeved on the surface of the rotating rod located inside the rotating groove.

[0012] Preferably, one end of the torsion spring is fixed to the stop block, and the other end of the torsion spring is fixed to the inner surface of the rotating groove. The length of the pull plate of the positioning member on one side of the rectangular frame is greater than the length of the pull plate of the positioning member on the other side of the rectangular frame. The rack is embedded in the rectangular groove, the retaining strip is embedded in the retaining groove, the gear meshes with the rack, and the insert is embedded in the positioning groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by setting up a vibration platform, support frame, rectangular frame, positioning components, and gears in a coordinated manner, when it is necessary to produce and test tall concrete products on the vibration platform, pulling one of the positioning components on the rectangular frame causes the positioning component to move. The rack drives the gear to rotate, and the rotating gear torsion spring. The gear then drives another positioning component to move until the posts of the positioning components on both sides of the rectangular frame disengage from the positioning slots of the rectangular frame. Then, the rectangular frame can be pulled up. Once the rectangular frame reaches the required height, the force pulling the positioning component is released. At this point, the gear will reverse under the action of the torsion spring, causing the posts of the positioning components to embed into the other positioning slot of the rectangular frame. This satisfies the usage requirements of the vibration platform. When it is necessary to clean the upper surface of the vibration platform, the rectangular frame is lowered to the same height as the vibration platform, facilitating cleaning.

A rubber pad is provided on the inner surface of the rectangular frame 5 to ensure a tight fit between the rectangular frame 5 and the vibration platform 2. The vibration platform 2 has longitudinally extending grooves 201 on its two side surfaces near the front and rear, in which the slider 501 is embedded. The rectangular frame 5 is movably connected to the vibration platform 2 via the slider 501. In conjunction with the slide 201, it can assist in the vertical lifting and lowering of the rectangular frame 5; the support frame 4 has a rectangular groove 401 inside, and a rotating groove 402 is provided inside the support frame 4 above and below the middle of the rectangular groove 401; the upper and lower surfaces of the rectangular groove 401 are provided with horizontal slots 403 near both sides; a right-angle rod 404 is fixedly installed on the lower surface of the support frame 4 near both ends, and the support frame 4 is fixed to the vibration platform 2 by the right-angle rod 404; the positioning component 6 includes a pull plate 602, a pin 603, a rack 601 and a locking strip 604, the pull plate 602... A rack 601 is fixedly installed on the inner surface of both ends. A retaining strip 604 is fixedly installed on the upper and lower surfaces of the rack 601. A plug 603 is fixedly installed on the inner surface of the pull plate 602 near the lower ends. The cooperation between the retaining strip 604 and the retaining groove 403 can assist the positioning part 6 to move smoothly. A rotating rod 701 is fixedly installed on the upper and lower surfaces of the gear 7. One end of the rotating rod 701 extends into the rotating groove 402. A stop block 702 is fixedly installed on the surface of one end of the rotating rod 701. A torsion spring 703 is sleeved on the surface of the rotating rod 701 located inside the rotating groove 402. One end of the torsion spring 703 is fixed to the stop block 702, and the other end of the torsion spring 703 is fixed to the inner surface of the rotating groove 402.
