Description

Technical Field

[0001] The utility model relates to the technical field of concrete transmission, and more specifically to a concrete transmission mechanism. Background Art

[0002] Concrete transfer refers to the process of transporting concrete from a container to the pouring location. Currently, when pouring some indoor secondary structure concrete, workers use small ground pumps to transfer concrete.

[0003] Common small floor pumps are mostly equipped with universal wheels for the convenience of transfer and use, which is convenient for workers to push, but they do not have additional support measures. When in use, they only rely on self-locking universal wheels to fix the position of the small floor pump. When workers pour concrete into the small floor pump, the concrete container will inevitably collide with the small floor pump. The small floor pump without additional support is more likely to move due to the collision of the concrete container, which may cause concrete leakage and waste. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a concrete transmission mechanism to solve the problem that the small ground pump lacking additional support in the above background technology is more likely to move due to the collision of the concrete container, which may cause concrete leakage.

[0005] The utility model provides the following technical solutions: a concrete transmission mechanism, including a ground pump assembly, a support assembly, a compensation assembly, and a power assembly, wherein the support assembly is arranged at the bottom of the ground pump assembly, the compensation assembly is arranged at the bottom of the support assembly, the power assembly is arranged at the bottom of the ground pump assembly, and the support assembly is connected to the power assembly;

[0006] The support assembly includes a support plate, a fixed block, two movable rods, and two sliding blocks. The fixed block is fixedly installed on the top of the support plate, one end of the two movable rods are rotatably installed in the fixed block, and the two sliding blocks are respectively rotatably installed at the other ends of the two movable rods. The floor pump assembly includes a floor pump body. A slide groove is opened at the bottom of the floor pump body, and the two sliding blocks are slidably installed in the slide groove.

[0007] Furthermore, the compensation assembly includes a contact plate and four springs. Four circular grooves are opened on the top of the contact plate, and the four springs are fixedly installed in the four circular grooves respectively. A square groove is opened on the bottom of the support plate, and the contact plate is slidably installed in the square groove. The four springs are fixedly connected to the bottom inner wall of the square groove.

[0008] Furthermore, the power assembly includes a bidirectional threaded rod and a motor. The bidirectional threaded rod is rotatably installed in a slide groove. Two sliding blocks are slidably sleeved on the outer wall of the bidirectional threaded rod through threads. An installation groove is opened at the bottom of the floor pump body. The motor is fixedly installed in the installation groove. The bidirectional threaded rod is fixedly connected to one end of the output shaft of the motor.

[0009] Furthermore, the floor pump assembly also includes two limit blocks, and the two limit blocks are fixedly installed in the slide groove.

[0010] Furthermore, the floor pump assembly also includes four support rods, which are all fixedly installed at the bottom of the floor pump body. The support assembly also includes four sliding sleeves, which are all fixedly installed at the top of the support plate.

[0013] Technical effects and advantages of the utility model:

[0014] The utility model starts the motor to drive the two-way threaded rod to rotate after the floor pump body is moved to the use position. The rotation of the two-way threaded rod can drive the two sliding blocks to slide close to each other in the slide groove through the thread. The sliding of the two sliding blocks will drive the two movable rods to approach each other. The approach of the two movable rods to each other will push the fixed block to slide downward, and then push the support plate to slide downward. In the process of the support plate sliding downward, the contact plate will first contact the ground. At this time, the support plate continues to slide downward and will compress the four springs. When the support plate also slides down to contact the ground, the spring can push the contact plate to make close contact with the ground. Through the support assembly and compensation assembly that are set, the staff can provide additional support for the floor pump body through the contact between the support plate and the contact plate and the ground, thereby improving the stability of the floor pump body, reducing the shaking of the floor pump body when it is hit, and avoiding leakage of concrete.

[0024] Figures 1 to 7 It is the best embodiment of the utility model, and the following Figures 1 to 7 The utility model is further described.

[0025] A concrete transmission mechanism includes a ground pump assembly 1, a support assembly 2, a compensation assembly 3, and a power assembly 4, wherein the support assembly 2 is arranged at the bottom of the ground pump assembly 1, the compensation assembly 3 is arranged at the bottom of the support assembly 2, the power assembly 4 is arranged at the bottom of the ground pump assembly 1, and the support assembly 2 is connected to the power assembly 4;

[0026] The support assembly 2 includes a support plate 201, a fixed block 202, two movable rods 203, and two sliding blocks 204. The fixed block 202 is fixedly installed on the top of the support plate 201. One ends of the two movable rods 203 are rotatably installed in the fixed block 202. The two sliding blocks 204 are respectively rotatably installed at the other ends of the two movable rods 203. The floor pump assembly 1 includes a floor pump body 101. A slide groove 102 is opened at the bottom of the floor pump body 101. The two sliding blocks 204 are both slidably installed in the slide groove 102.

[0027] Specifically, the compensation component 3 includes a contact plate 301 and four springs 303. Four circular grooves 302 are opened on the top of the contact plate 301. The four springs 303 are fixedly installed in the four circular grooves 302 respectively. A square groove 207 is opened on the bottom of the support plate 201. The contact plate 301 is slidably installed in the square groove 207. The four springs 303 are fixedly connected to the bottom inner wall of the square groove 207.

[0028] Specifically, the power assembly 4 includes a bidirectional threaded rod 401 and a motor 402. The bidirectional threaded rod 401 is rotatably installed in the slide groove 102. The two sliding blocks 204 are both slidably sleeved on the outer wall of the bidirectional threaded rod 401 through threads. An installation groove 104 is opened at the bottom of the floor pump body 101. The motor 402 is fixedly installed in the installation groove 104. The bidirectional threaded rod 401 is fixedly connected to one end of the output shaft of the motor 402.

[0029] In this embodiment, the motor 402 is started to drive the bidirectional threaded rod 401 to rotate. The rotation of the bidirectional threaded rod 401 can drive the two sliding blocks 204 to slide close to each other in the slide groove 102 through the thread. The sliding of the two sliding blocks 204 will drive the two movable rods 203 to approach each other. The approaching of the two movable rods 203 will push the fixed block 202 to slide downward, and then push the support plate 201 to slide downward. In the process of the support plate 201 sliding downward, the contact plate 301 will first contact the ground. At this time, the support plate 201 continues to slide downward, which will compress the four springs 303. When the support plate 201 also slides down to contact the ground, the spring 303 can push the contact plate 301 to make close contact with the ground.

[0030] Specifically, the floor pump assembly 1 further includes two limit blocks 103 , and the two limit blocks 103 are both fixedly installed in the slide groove 102 .

[0031] In this embodiment, the limit block 103 can provide a limit for the sliding of the two sliding blocks 204. When the two sliding blocks 204 slide to contact the two limit blocks 103 respectively, the support plate 201 will just slide down to contact the ground.

[0032] Specifically, the floor pump assembly 1 also includes four support rods 105, which are all fixedly installed at the bottom of the floor pump body 101. The support assembly 2 also includes four sliding sleeves 205, which are all fixedly installed at the top of the support plate 201. Four through holes 206 are opened at the bottom of the support plate 201, and the support rods 105 are slidably inserted between the sliding sleeves 205 and the inner walls of the through holes 206.

[0033] In this embodiment, the support rod 105 can provide support to the support plate 201 during the process of the support plate 201 sliding downward and after the support plate 201 slides downward to contact the ground, thereby improving the stability of the support plate 201.

[0034] Specifically, the floor pump assembly 1 further includes a plurality of screening rods 106 , and the plurality of screening rods 106 are evenly distributed in the feed port of the floor pump body 101 .

[0035] In this embodiment, the screening rod 106 is provided to screen out oversized stones in the concrete, thereby preventing the stones from clogging the ground pump body 101 .

[0036] Specifically, a plurality of anti-skid pads 5 are evenly distributed on the bottom of the contact plate 301 .

[0037] In this embodiment, the anti-slip pad 5 is provided to increase the friction between the contact plate 301 and the ground.

[0038] Working principle: after the floor pump body 101 is moved to the use position, the motor 402 is started to drive the bidirectional threaded rod 401 to rotate. The rotation of the bidirectional threaded rod 401 can drive the two sliding blocks 204 to slide close to each other in the slide groove 102 through the thread. The sliding of the two sliding blocks 204 will drive the two movable rods 203 to approach each other. The two movable rods 203 approaching each other will push the fixed block 202 to slide downward, and then push the support plate 201 to slide downward. In the process of the support plate 201 sliding downward, the contact plate 301 will first contact the ground. At this time, the support plate 201 continues to slide downward and compresses the four springs 303. When the support plate 201 also slides down to contact the ground, the spring 303 can push the contact plate 301 to make close contact with the ground. Through the support assembly 2 and the compensation assembly 3, the staff can provide additional support for the floor pump body 101 through the contact between the support plate 201 and the contact plate 301 and the ground, thereby improving the stability of the floor pump body 101, reducing the shaking of the floor pump body 101 when it is hit, and avoiding the leakage of concrete.
