Description

Technical Field

[0001] The invention relates to the technical field of civil engineering test and detection, in particular to a concrete test block demoulding device and a demoulding method thereof. Background Art

[0002] With the development of social economy, domestic engineering infrastructure has become huge in scale and has many projects. In engineering construction, concrete is undoubtedly a very important building material. In order to facilitate the detection of concrete strength, a corresponding amount of concrete test blocks need to be retained during the construction process.

[0003] In the process of demolding concrete test blocks, the commonly used method is air pump demolding, and it is necessary to manually adjust and move the position of the test mold and the air pump port continuously, or because the test block is firmly attached to the test mold, the air pump cannot blow out the test block at one time, and manual shaking and vibration are required to demold the test block. The process consumes a lot of time and manpower, and conventional operations can no longer meet the needs of convenience. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art, provide a concrete test block demoulding device and a demoulding method thereof, and solve the problem that the demoulding operation of the concrete test block in the prior art is difficult.

[0005] To achieve the above-mentioned object, the present invention provides a concrete test block demoulding device, which is used to separate the formed concrete test block from the test mold with a second air inlet, and the demoulding device includes a fixed back plate, a test block demoulding seat, a first air inlet and a high-pressure air gun;

[0006] The test block demoulding seat is movably connected to one side of the fixed back plate;

[0007] The test block demoulding seat is clamped on the test mold;

[0008] The first air inlet is opened through the top of the test block demoulding seat, and the first air inlet corresponds to the second air inlet on the top of the test mold after the test mold is placed in the accommodating cavity;

[0009] The air outlet end of the high-pressure air gun cooperates with the first air inlet, and the air inlet end of the high-pressure air gun is connected to the air source through an air pipe.

[0010] By adopting this technical solution, after the concrete test block is formed in the test mold, the test mold can be clamped on the lower side of the test block demoulding seat with the second air inlet facing upward, and then the air outlet end of the high-pressure air gun is matched with the first air inlet on the test block demoulding seat. After the air source supplies gas to the high-pressure air gun, the high-pressure air gun is started, and the high-pressure gas passes from the first air inlet to the second air inlet to directly act on the concrete test block inside the test mold, thereby manually moving the test block demoulding seat on the fixed back plate to generate shaking to separate the concrete test block from the test mold, thereby achieving the purpose of demoulding the concrete test block. Not only is the operation simple, but also the labor intensity is reduced.

[0011] Furthermore, there are multiple second air inlets on the test mold, and the demolding device also includes an air separation component connected to the test block demolding seat, and the high-pressure gas introduced from the first air inlet is diverted to the corresponding second air inlet through the air separation component.

[0012] By adopting this technical solution, the prerequisite is provided for demoulding multiple concrete test blocks at the same time.

[0013] Furthermore, the gas distribution component includes a flow distribution block, a main air inlet and a plurality of flow distribution outlets;

[0014] A cavity is provided inside the diverter block;

[0015] The main air inlet is arranged at the top of the diverter block, and the first air inlet and the cavity are connected through the main air inlet;

[0016] The plurality of split air outlets correspond to the plurality of the second air inlets one by one and are disposed at the bottom of the split block, and the split air outlets are connected to the cavity;

[0017] A control valve is arranged in the split gas outlet.

[0018] By adopting this technical solution, the diversion of the gas introduced from the first air inlet is achieved through the cooperation of the diverter block, the main air inlet and multiple diverter outlets, which can adapt to the situation where there are multiple second air inlets on the test mold; a control valve is set on the diverter outlet to control the air outlet, avoiding the situation where a single concrete test block cannot be demoulded using the device due to too many air outlet positions.

[0019] Furthermore, the demoulding device also includes a guide rail and a slider:

[0020] The guide rail is fixed to the fixed back plate;

[0021] The slide block is slidably connected to the guide rail, and the slide block is fixedly connected to the test block demoulding seat.

[0022] By adopting this technical solution, the guide rail and the slider cooperate to realize the movable connection of the test block demoulding seat on the fixed back plate.

[0023] Furthermore, a mounting hole is vertically opened on the fixed back plate.

[0024] By adopting this technical solution, the fixed back plate can be fixed on any vertical base surface with bolts, thereby reducing the difficulty of installing the device.

[0025] Furthermore, the test block demoulding seat is in an inverted U shape, and the lower ends on both sides thereof are connected with inner support bars for supporting the bottom of the test mold, thereby completing the clamping of the test mold on the test block demoulding seat.

[0026] By adopting this technical solution, the inner support bar provides upward support, thereby preventing the test mold from falling downward, thereby achieving the clamping of the test mold.

[0027] Furthermore, the air outlet of the high-pressure air gun is provided with a quick-connect male connector, and the top of the first air inlet is provided with a quick-connect female connector;

[0028] The air outlet end of the high-pressure air gun is connected to the first air inlet through the cooperation of the quick-connect male connector and the quick-connect female connector.

[0029] By adopting this technical solution, the degree of coordination between the high-pressure air gun and the first air inlet is increased, while the difficulty of coordination between the high-pressure air gun and the first air inlet is reduced.

[0030] The present invention also provides a demoulding method for a concrete test block demoulding device, which is characterized by comprising the following steps:

[0031] S1, placing the test mold with the formed concrete test block into the test block demoulding seat;

[0032] S2, connecting the high-pressure air gun connected to the air source to the first air inlet;

[0033] S3, starting the high-pressure air gun to supply air to the first air inlet;

[0034] S4, shaking the test block demoulding seat back and forth to drive the test mold to shake until the formed concrete test block falls off;

[0035] S5. Take out the test mold and complete the demoulding operation of the concrete test block.

[0036] Furthermore, the step S1 includes:

[0037] The position of the trial mold is adjusted until the second air inlet at the top thereof is connected to the first air inlet.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. In the present application, when high-pressure gas acts on the concrete test block in the test mold, the relative movement of the test block demoulding seat and the fixed back plate is controlled to cause the concrete test block to vibrate relative to each other, thereby accelerating the demoulding of the concrete test block in the test mold and reducing the difficulty of demoulding the concrete test block and the labor intensity.

[0040] 2. The present application sets up an air distribution component to perform air intake diversion, and any diversion outlet is individually provided with a control valve, which can not only adapt to the situation where a single concrete test block corresponds to multiple second air inlets for demolding, but also adapt to the simultaneous demolding of multiple concrete test blocks, and has high applicability.
