Description

Technical Field

[0001] The present application relates to the technical field of concrete testing, and in particular to a concrete boiling test device. Background Art

[0002] In concrete quality testing, the boiling method is often used to test the volume stability of concrete. Boiling requires placing the concrete test block in boiling water and keeping it warm for several hours before testing. For this purpose, people have designed a variety of concrete boiling experimental devices, such as a concrete boiling box disclosed in Chinese patent application number 202020770090.3, which uses a chain collector and a chain to lift and lower the boiling grid, making it convenient to take out the concrete test block after boiling and heating. However, the chain collector and the chain can only move in the vertical direction. Even after the boiling grid is raised, it is still far from the ground. The operator still needs to put the concrete test block into the boiling grid, which is labor-intensive. For example, a concrete boiling box disclosed in a Chinese patent application number 201822163355.9 realizes the lifting and lowering of a receiving platform through a cylinder, and at the same time, the lower part of the cylinder can rotate, and the receiving platform can rotate after being raised, so that the receiving platform can be transferred to one side of the equipment, which is convenient for taking and placing concrete test blocks and reducing the labor intensity of operators. However, the device only supports the receiving platform through a cylinder, and the receiving platform for placing concrete test blocks is heavy, which can easily bend the top rod of the cylinder and cause the sealing component to deform and leak, resulting in a short service life of the equipment. At the same time, the overall weight of the receiving platform after the concrete test block is placed is between 100kg and 150kg. After the cylinder is extended, the force arm is long, and it is not easy to bend even if the handle is long, which increases the labor intensity of the operator. Utility Model Content

[0006] Furthermore, the main slide rail is provided with a long strip of slots, the transmission plate extends outward through the slots and is connected to the screw rod, the main slide rail is provided with a trapezoidal slot, and the shape of the auxiliary slide rail is adapted to the trapezoidal slot.

[0011] Furthermore, the carrying basket is a steel rectangular parallelepiped structure, and a plurality of openings are provided on the carrying basket.

[0012] The beneficial effects of the present application are as follows: by using a main slide rail and a secondary slide rail that can interact with each other, and cooperating with a motor and a screw, the lifting and lowering of the carrying basket can be achieved, and at the same time, the main slide rail is driven to swing by a hydraulic cylinder, so that the carrying basket can be moved from the boiling box to the carrying platform, which is convenient for operators to take and place concrete blocks and reduces the labor intensity of operators.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a concrete boiling experimental device, comprising: a boiling box 1, a carrying basket 2, a main slide rail 3, and an auxiliary slide rail 4, wherein the main slide rail 3 is hinged at the lower part of both sides of the boiling box 1, and the auxiliary slide rail 4 is slidably installed in the main slide rail 3, and the upper parts of the auxiliary slide rails 4 are mutually connected by connecting rods 5, and the upper part of the carrying basket 2 is connected to the connecting rod 5; a motor 6 and a screw rod 7 are provided on one side of the main slide rail 3, and both ends of the screw rod 7 are connected to the main slide rail 3 through bearings, the motor 6 is installed on the upper side of the main slide rail 3, and the output shaft of the motor 6 is connected to the screw rod 7, and a transmission plate 8 is provided at the lower part of the auxiliary slide rail 4, and a threaded hole is provided in the middle part of the transmission plate 8, and the transmission plate 8 is connected to the screw rod 7 through threads.

[0022] The size of the concrete test block specified in the national standard is 100mm×100mm×100mm, and the weight is 7-8kg. When the operator needs to put the concrete test block into the boiling box 1, the operator controls the motor 6 to drive the screw 7 to rotate through the control switch, thereby driving the auxiliary slide rail 4 to slide through the transmission plate 8, so that the auxiliary slide rail 4 extends and drives the carrying basket 2 to rise, and then the hydraulic cylinder 9 extends, thereby pushing the main slide rail 3 to drive the auxiliary slide rail 4 to swing, so that the carrying basket 2 moves to the carrying platform 11 outside the boiling box 1, so that the operator can put the concrete test block into the carrying basket 2. After stacking the concrete test blocks, the operator controls the hydraulic cylinder 9 to contract, thereby pulling the main slide rail 3 from an inclined state to a vertical state, and then the motor 6 rotates, so that the screw 7 drives the transmission plate 8 to move downward, so that the carrying basket 2 descends into the boiling box 1, and after heating water through the heating pipe in the boiling box 1, the concrete test block is heated, thereby detecting the volume stability of the concrete. After boiling for a specified time, the carrying basket 2 is moved to the carrying platform 11 according to the above steps, so that the operator can take out the concrete test block from the carrying basket 2 conveniently.

[0023] In a preferred embodiment, Figure 2 As shown, the main slide rail 3 is provided with a long slot, and the transmission plate 8 extends outward through the slot and is connected to the screw 7. The long slot facilitates the movement of the transmission plate 8 therein. The main slide rail 3 is provided with a trapezoidal slot, and the shape of the auxiliary slide rail 4 is adapted to the trapezoidal slot, so that after the main slide rail 3 and the auxiliary slide rail 4 are connected, the auxiliary slide rail 4 can only slide along the long direction of the main slide rail 3, and can provide supporting force to ensure the stability of the supporting basket 2 during deflection.

[0024] Preferably, hydraulic cylinders 9 are provided on both sides of the boiling box 1, one end of the hydraulic cylinder 9 is hinged to the boiling box 1, and the other end is hinged to the main slide rail 3. The hydraulic cylinder 9 provides power so that the main slide rail 3 and the auxiliary slide rail 4 can drive the supporting basket 2 to swing, thereby reducing the labor intensity of the operator.

[0025] In a specific embodiment, the hydraulic cylinder 9 is used to push the main slide rail 3 to swing, and limit plates 10 are provided on both sides of the boiling box 1. The limit plates 10 are used to limit the swing range of the main slide rail 3. After limiting, the main slide rail 3 can only swing with the limit plates 10, which is convenient for controlling the angle of the main slide rail 3.

[0026] Specifically, a connecting frame 12 is provided on the side of the boiling box 1, and the hydraulic cylinder 9 is hinged to the boiling box 1 through the connecting frame 12. The connecting frame 12 provides an installation position to facilitate the installation of a longer hydraulic cylinder 9, so that the telescopic length of the hydraulic cylinder 9 is longer, so that the main slide rail 3 can be pushed to swing with a longer force arm.

[0027] Specifically, Figure 3As shown, it also includes a bearing platform 11, which is installed on one side of the boiling box 1. The bearing platform 11 is used to support the bearing basket 2. The main slide rail 3 is subjected to a large torque when it is in an inclined state, and it is easy to impact the main slide rail 3 and the auxiliary slide rail 4 when loading concrete. Therefore, the bearing basket 2 is placed on the bearing platform 11 to reduce the impact of the concrete test block on the main slide rail 3, the auxiliary slide rail 4, and the hydraulic cylinder 9 when loading or taking out.

[0028] Preferably, the supporting basket 2 is a steel rectangular parallelepiped structure, and a plurality of openings are provided on the supporting basket 2, so that boiling water can enter the supporting basket 2 through the openings to heat the concrete test block.

[0029] Preferably, if Figure 4 As shown, the boiling box 1 is also provided with a box cover, which can prevent the boiling water from splashing, while improving the heat preservation performance of the boiling box 1 and reducing power consumption.

[0030] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
