Description

Technical Field

[0001] The utility model relates to the technical field of post-cast strip construction, in particular to an independent support device for post-cast strips. Background Technique

[0002] The independent support device for post-cast strips is a temporary support system used in the construction industry. It is mainly used in the construction process of concrete structures, especially when pouring post-cast strips (also known as construction joints). A post-cast strip is a strip-shaped area reserved in the concrete structure where concrete is not poured temporarily. The purpose is to reduce cracks in the concrete caused by factors such as temperature changes and shrinkage.

[0003] Traditional support devices usually have a fixed height or a limited adjustment range, which is not convenient to meet the needs of different construction heights. When the support height needs to be adjusted, it may be necessary to rebuild the support system, which is time-consuming and laborious. Traditional devices may not be convenient to adapt to post-cast strips of different widths, resulting in poor support effects or inconvenient use.

[0004] Therefore, those skilled in the art have provided an independent support device for post-cast strips to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the content of the utility model is to solve the deficiencies existing in the prior art, and a kind of independent support device for post-cast strips is proposed. The operator starts the first servo motor through an external controller to drive the double-headed worm to rotate. The double-headed worm will drive the worm wheels at both ends to rotate. Subsequently, the worm wheels at both ends will drive the threaded rods to rotate, and then the entire support device will be lifted and lowered, so that the support device can be adjusted to any height.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An independent support device for post-cast strips includes a lifting mechanism and an adjusting mechanism. The lifting mechanism includes a base. At the front and rear of the upper end of the middle part of the base, limiting plates are fixedly connected. At the rear end of the front limiting plate, a first servo motor is fixedly connected. The output end of the first servo motor is fixedly connected with a double-headed worm. The rear end of the double-headed worm is rotationally connected with the front end of the rear limiting plate. Worm wheels are arranged on the front and rear outer walls of the double-headed worm. The worm wheels are meshed with the double-headed worm. Threaded rods are fixedly connected to the middle parts of the worm wheels. Fixed seats are fixedly connected to the four corners of the upper end of the base. Slide rods are fixedly connected to the inner walls of the fixed seats. An adjusting mechanism is arranged at the upper end of the lifting mechanism;

[0008] Through the above technical solution, the operator starts the first servo motor through an external controller to drive the double-headed worm to rotate. The double-headed worm will drive the worm wheels at both ends to rotate. Subsequently, the worm wheels at both ends will drive the threaded rod to rotate, and then the entire support device will be lifted or lowered, so that the support device can be adjusted to any height, meeting the usage requirements in different situations, thus achieving the purpose of flexibly adjusting the height, without having to re-erect the support system. At the same time, the sliding rod plays a certain auxiliary role in fixing the lifting of the support device.

[0009] Furthermore, the adjusting mechanism includes a sliding seat. The rod body of the threaded rod is threadedly connected to the inside of the sliding seat. The rod body of the sliding rod is slidably connected to the inside of the sliding seat. A first sliding groove is formed in the middle of the sliding seat. A second servo motor is fixedly connected to the front end of the inner wall of the first sliding groove. The output end of the second servo motor is fixedly connected to a bidirectional threaded rod. Threaded blocks are threadedly connected to both the front and rear parts of the rod body of the bidirectional threaded rod. Connecting rods are fixedly connected to the middle parts of the upper ends of the threaded blocks. The upper ends of the connecting rods are fixedly connected to a supporting plate. Second sliding grooves are formed at one ends of adjacent supporting plates.

[0010] Through the above technical solution, the operator starts the second servo motor through an external controller to drive the bidirectional threaded rod to rotate, and then drives the threaded blocks and the supporting plates at both ends to move towards or away from each other, so as to adjust the distance between the two supporting plates, thus meeting the support requirements for post-cast strips of different widths. And according to the adjusted width, while cooperating with the limiting block to slide on the inner wall of the limiting groove, the supporting plate can be limited to prevent the occurrence of a certain phenomenon, ensuring the strength of the support and good stability.

[0011] Furthermore, fixing bolts are arranged on the inner walls of the fixed seats.

[0012] Through the above technical solution, the fixing bolts can be used to fix other components of the support device, ensuring that these components will not have relative displacement during operation, thus maintaining the stability and reliability of the support device.

[0013] Furthermore, one end of the bidirectional threaded rod away from the second servo motor is rotatably connected to the rear end of the inner wall of the first sliding groove.

[0014] Through the above technical solution, the rotational connection of the bidirectional threaded rod allows the operator to control the second servo motor to realize the movement of the threaded blocks and the supporting plates towards or away from each other in two directions, thereby adjusting the width of the support device.

[0015] Furthermore, limiting grooves are formed on both sides of the inner wall of the second sliding groove. Supporting plates are slidably connected to the inner walls of the second sliding grooves.

[0016] Through the above technical solution, the limit groove can prevent the support plate from accidentally falling off due to external forces during the adjustment process, ensuring the stability of the support. The sliding connection of the support plate allows for precise adjustment of the support height to adapt to floor slabs or beams of different thicknesses.

[0017] Further, both sides of the front and rear of the support plate are fixedly connected with limit blocks, and the outer walls of the limit blocks are slidably connected with the inner walls of the limit grooves;

[0018] Through the above technical solution, the sliding connection between the limit blocks and the limit grooves ensures that the support plate will not slide excessively in the chute, thus maintaining the accuracy of the support position. Through the limitation of the limit blocks, the support plate is more stable when bearing loads, reducing displacement caused by vibration or external forces.

[0019] Further, a storage battery is arranged at the rear part of the upper end of the base;

[0020] Through the above technical solution, the storage battery can ensure that the device continues to work in case of power interruption, reducing interruptions and delays during the construction process.

[0021] Further, braking universal wheels are fixedly connected to the four corners of the lower end of the base;

[0022] Through the above technical solution, the braking universal wheels enable the support device to move flexibly on uneven ground or in narrow spaces, improving the convenience of construction. The 360-degree rotation ability of the braking universal wheels allows the operator to quickly and accurately position the support device.

[0023] The utility model has the following beneficial effects:

[0024] 1. For an independent support device for post-cast strips proposed by the utility model, the operator starts the first servo motor through an external controller to drive the double-headed worm to rotate. The double-headed worm will drive the worm wheels at both ends to rotate. Subsequently, the worm wheels at both ends will drive the threaded rods to rotate, thereby lifting the entire support device, so that the support device can be adjusted to any height, meeting the usage requirements in different situations, thus achieving the purpose of flexibly adjusting the height, without the need to re-erect the support system. At the same time, the sliding rod plays a certain auxiliary role in fixing the lifting of the support device.

[0025] 2. For an independent support device for post-cast strips proposed by the utility model, the operator starts the second servo motor through an external controller to drive the bidirectional threaded rod to rotate, and then drives the sliders and the top support plates at both ends to move towards or away from each other, which can adjust the distance between the two top support plates, thus meeting the support requirements for post-cast strips of different widths. And according to the adjusted width, while cooperating with the limit blocks to slide on the inner wall of the limit groove, the support plate can be limited to prevent the occurrence of phenomena, ensuring the strength of the support and good stability.

[0037] Refer to Figure 1 、Figure 2 and Figure 6 , a specific embodiment provided by the present utility model:

[0038] A post-cast strip independent support device includes a lifting mechanism 1 and an adjusting mechanism 2. The lifting mechanism 1 includes a base 101. Front and rear parts of the upper end of the middle base 101 are fixedly connected with limiting plates 104. The rear end of the front limiting plate 104 is fixedly connected with a first servo motor 105. The output end of the first servo motor 105 is fixedly connected with a double-headed worm 107. The rear end of the double-headed worm 107 is rotationally connected with the front end of the rear limiting plate 104. Outer walls of the front and rear parts of the double-headed worm 107 are provided with worm wheels 106. The worm wheels 106 are meshed with the double-headed worm 107. Middle parts of the worm wheels 106 are fixedly connected with threaded rods 108. Fixing seats 110 are fixedly connected to four corners of the upper end of the base 101. Inner walls of the fixing seats 110 are fixedly connected with sliding rods 109. The upper end of the lifting mechanism 1 is provided with the adjusting mechanism 2;

[0039] The operator starts the first servo motor 105 through an external controller to drive the double-headed worm 107 to rotate. The double-headed worm 107 will drive the worm wheels 106 at both ends to rotate. Then the worm wheels 106 at both ends will drive the threaded rods 108 to rotate, thereby lifting the entire support device, so that the support device can be adjusted to any height, meeting the usage requirements in different situations, thus achieving the purpose of flexibly adjusting the height, without having to re-erect the support system. At the same time, the sliding rods 109 play a certain auxiliary role in fixing the lifting of the support device.

[0040] Refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7, the adjusting mechanism 2 includes a sliding seat 201. The rod body of the threaded rod 108 is threadedly connected to the inside of the sliding seat 201, and the rod body of the sliding rod 109 is slidably connected to the inside of the sliding seat 201. A first sliding groove 204 is formed in the middle of the sliding seat 201. A second servo motor 202 is fixedly connected to the front end of the inner wall of the first sliding groove 204. The output end of the second servo motor 202 is fixedly connected to a bidirectional threaded rod 203. The front and rear parts of the rod body of the bidirectional threaded rod 203 are both threadedly connected with sliders 205. The middle parts of the upper ends of the sliders 205 are fixedly connected with connecting rods 207, and the upper ends of the connecting rods 207 are fixedly connected with supporting plates 206. Second sliding grooves 210 are formed at one ends of adjacent supporting plates 206. The operator starts the second servo motor 202 through an external controller to drive the bidirectional threaded rod 203 to rotate, and then drives the sliders 205 and the supporting plates 206 at both ends to move towards or away from each other, so as to adjust the distance between the two supporting plates 206, thereby meeting the support requirements of post-cast strips with different widths. And according to the adjusted width, at the same time, in cooperation with the sliding of the limiting block 209 on the inner wall of the limiting groove 211, the supporting plate 208 can be limited to prevent the phenomenon from occurring, which can ensure the support strength and good stability. Fixed bolts 111 are arranged on the inner walls of the fixed seats 110. The fixed bolts 111 can be used to fix other components of the support device to ensure that these components will not have relative displacement during operation, thereby maintaining the stability and reliability of the support device;

[0041] One end of the bidirectional threaded rod 203 away from the second servo motor 202 is rotatably connected to the rear end of the inner wall of the first chute 204.

Limiting blocks 209 are fixedly connected to both sides of the front and rear of the supporting plates 208. The outer walls of the limiting blocks 209 are slidably connected to the inner walls of the limiting grooves 211. The slidable connection between the limiting blocks 209 and the limiting grooves 211 ensures that the supporting plates 208 will not slide excessively in the chute, thereby maintaining the accuracy of the support position. Through the limitation of the limiting blocks 209, the supporting plates 208 are more stable when bearing loads, reducing displacement caused by vibration or external forces. A storage battery 103 is provided at the rear part of the upper end of the base 101. The storage battery 103 can ensure that the device continues to work in the event of a power outage, reducing interruptions and delays during construction. Brake universal wheels 102 are fixedly connected to the four corners of the lower end of the base 101. The brake universal wheels 102 enable the supporting device to move flexibly on uneven ground or in narrow spaces, improving the convenience of construction. The 360-degree rotation ability of the brake universal wheels 102 allows the operator to quickly and accurately position the supporting device.

[0042] Working principle: The operator starts the first servo motor 105 through an external controller to drive the double-headed worm 107 to rotate. The double-headed worm 107 will drive the worm wheels 106 at both ends to rotate. Subsequently, the worm wheels 106 at both ends will drive the threaded rod 108 to rotate, and then the entire supporting device will be lifted or lowered, so that the supporting device can be adjusted to any height, meeting the usage requirements in different situations, thereby achieving the purpose of flexibly adjusting the height without having to re-erect the support system. At the same time, the sliding rod 109 plays a certain auxiliary role in fixing the lifting of the supporting device. At the same time, the operator starts the second servo motor 202 through an external controller to drive the bidirectional threaded rod 203 to rotate, and then drives the sliders 205 and the supporting plates 206 at both ends to move towards or away from each other, which can adjust the distance between the two supporting plates 206, thereby meeting the support requirements for post-cast strips of different widths. And according to the adjusted width, at the same time, in cooperation with the sliding of the limiting blocks 209 on the inner wall of the limiting grooves 211, the supporting plates 208 can be limited to prevent the occurrence of phenomena, which can ensure the strength of the support and good stability.
