Description

Technical Field

[0001] The utility model relates to the technical field of load boxes, in particular to a self-balancing load box which can conveniently recover hydraulic oil. Background Art

[0002] The self-balancing load box is a device used for testing large-diameter cast-in-place pile foundations. It mainly uses a pressure pump to pressurize the ground to generate a loading force inside the pile. By calculating and analyzing the relationship between the loading force and various parameters, not only can the pile foundation bearing capacity be obtained, but also a series of data such as the lateral resistance coefficient of each soil layer, the lateral resistance of the pile, and the pile end bearing capacity can be obtained. These data can not only provide data basis for design, but also can be used to test the bearing capacity of engineering piles.

[0003] When the self-balancing load box is in operation, it is usually buried deep underground. The self-balancing load box that can easily recycle hydraulic oil contains a jack cylinder. If the jack cylinder is placed underground for a long time, it may leak oil, pollute groundwater and soil under the long-term infiltration and diffusion of rainwater and groundwater, and reduce the environmental function level of the area. Therefore, it is necessary to remove the self-balancing load box after the operation is completed. However, since it is buried deep underground, it is very labor-intensive and labor-intensive to remove it. How to solve the oil leakage pollution caused by the long-term placement of the jack cylinder has become an urgent problem to be solved. Utility Model Content

[0004] In order to solve the above problems of the prior art, the utility model provides a self-balancing load box which can conveniently recycle hydraulic oil, and can easily and cheaply remove the oil in the jack cylinder of the self-balancing load box, thereby greatly reducing environmental pollution.

[0005] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a self-balancing load box that can conveniently recover hydraulic oil, including a jack cylinder, a one-way feed valve, a one-way discharge valve, a feed pipe, a discharge pipe, a valve switch controller and a remote control switch;

[0006] A one-way feed valve and a one-way discharge valve are respectively provided on the top of the two side walls of the jack cylinder, the feed pipe and the discharge pipe are respectively connected to the one-way feed valve and the one-way discharge valve, the valve switch is arranged on the side wall of the jack cylinder, the valve switch controller is respectively connected to the one-way feed valve and the one-way discharge valve, and is used to control the switch of the one-way feed valve and the one-way discharge valve, and the remote control switch is electrically connected to the valve switch controller.

[0007] The beneficial effect of the utility model is that when the self-balancing load box is buried underground, the far ends of the feed pipe and the discharge pipe and the remote control switch need to be placed above the ground. After the balanced load box is buried, the valve switch controller is controlled by the remote control switch to open the one-way feed valve and the one-way discharge valve, and cement slurry is injected into the feed pipe. The cement slurry enters the jack cylinder along the feed pipe, and the hydraulic oil in the jack cylinder is squeezed out from the discharge pipe, thereby realizing low-cost and convenient oil pumping operations and protecting the soil environment.

[0008] Preferably, the remote control switch is electrically connected to the valve switch controller via an electric wire.

[0009] From the above description, it can be seen that the electrical connection between the remote control switch and the valve switch controller is achieved through wires, which ensures the stability of communication.

[0010] Preferably, it also includes a feed hopper;

[0011] The feed hopper is connected to the inlet of the feed pipe.

[0012] It can be seen from the above description that the feeding operation of the feeding pipe is facilitated by the feeding hopper. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0017] Embodiment 1

[0018] Please refer to Figure 1 As shown, a self-balancing load box capable of conveniently recovering hydraulic oil comprises a jack cylinder 1, a one-way feed valve 2, a one-way discharge valve 3, a feed pipe 4, a discharge pipe 5, a valve switch controller 7 and a remote control switch 9;

[0019] A one-way feed valve 2 and a one-way discharge valve 3 are respectively provided on the top of the two side walls of the jack cylinder 1, the feed pipe 4 and the discharge pipe 5 are respectively connected to the one-way feed valve 2 and the one-way discharge valve 3, the valve switch is arranged on the side wall of the jack cylinder 1, the valve switch controller 7 is respectively connected to the one-way feed valve 2 and the one-way discharge valve 3, and is used to control the switch of the one-way feed valve 2 and the one-way discharge valve 3, and the remote control switch 9 is electrically connected to the valve switch controller 7.

[0020] Preferably, the remote control switch 9 is electrically connected to the valve switch controller 7 via an electric wire 8 .

[0021] Preferably, it also includes a feed hopper 6;

[0022] The feed hopper 6 is connected to the inlet of the feed pipe 4 .

[0023] The working principle of the utility model is as follows:

[0024] When the self-balancing load box is buried underground, it is necessary to place the far ends of the feed pipe 4, the discharge pipe 5 and the remote control switch 9 above the ground. After the burying of the balanced load box is completed, the valve switch controller 7 is controlled by the remote control switch 9 to open the one-way feed valve 2 and the one-way discharge valve 3, and cement slurry is injected into the feed pipe 4. The cement slurry enters the jack cylinder 1 along the feed pipe 4, and the hydraulic oil in the jack cylinder 1 is squeezed out from the discharge pipe 5. After that, since the self-balancing load box basically does not cause pollution to the soil, it will cost a lot to take it out from the ground. Therefore, from a cost perspective, there is no need to take it out from deep underground.

[0025] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
