Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to an independent supporting frame. Background Art

[0002] In building construction, in order to complete the construction better and faster, more and more modular concrete casting molds are used, such as composite floor molds, composite beam molds, etc. When using a casting mold, it is necessary to support it from below through a supporting device to prevent it from falling. The tripod is a supporting device that plays an independent supporting role.

[0003] In construction, a lifting tripod is often used as a supporting device. Its supporting tube consists of a supporting bottom tube and a sliding tube. The sliding tube can move axially along the supporting bottom tube, so that the overall height of the tripod can be adjusted according to the situation on site. At present, the first way to adjust the height is to hold the sliding tube and slide it upward, and limit the movement of the sliding tube at the required height position; the other way is to use mechanical force to raise the sliding tube, and the mechanical force stops at the required height position. Both of these height adjustment methods have a defect: when the sliding tube is used to adjust the height, when the sliding tube overlaps less with the supporting bottom tube, the supporting bottom tube cannot support the sliding tube because the sliding tube is long and heavy, and the sliding tube is easy to break away from the supporting bottom tube and fall over, which is especially easy to happen in higher construction. Although a warning mark is made on the upper limit position of the sliding tube, the operator is prone to negligence and accidents. Summary of the invention

[0035] See also Figure 1 and Figure 2 In one embodiment, the independent support frame includes: a supporting bottom tube 1, a sliding tube 2, a positioning structure 3 and a height adjustment device 6.

[0036] The support bottom tube 1 is a hollow tube. Preferably, a bottom plate is fixedly installed at the bottom of the support bottom tube 1, and the bottom plate allows the support bottom tube 1 to be placed stably on the ground. A positioning hole 11 is provided on the upper part of the support bottom tube 1. Preferably, the positioning hole 11 is set at a position about one tenth of the length of the support bottom tube 1 from the top of the support bottom tube 1, which can ensure that a certain length of the sliding tube 2 is retained in the support bottom tube 1 and the sliding tube 2 will not fall over.

[0037] The sliding tube 2 is slidably installed in the supporting bottom tube 1, and the sliding tube 2 moves axially in the supporting bottom tube 1. The sliding tube 2 is provided with a groove 21 extending along its axial direction, and a baffle 22 is fixedly installed at the bottom end of the sliding tube 2. Preferably, the diameter of the baffle 22 is the same as that of the sliding tube 2, and the baffle 22 covers the groove 21. Preferably, a bearing plate is provided at the top end of the sliding tube 2 to increase the contact area with the mold to be poured.

[0038] The positioning structure 3 passes through the positioning hole 11 and is embedded in the groove 21 . The positioning structure 3 cooperates with the baffle 22 , thereby limiting the axial movement of the sliding tube 2 along the supporting bottom tube 1 .

[0039] In one embodiment, the independent support frame includes a support foot 4 and a plurality of support feet 5. The support foot 4 is slidably mounted on the outside of the support bottom tube 1, and the support foot 4 moves axially along the support bottom tube 1. A plurality of U-shaped blocks are evenly spaced and installed on the outside of the support foot 4, and the support feet 5 are hingedly mounted on the U-shaped blocks, so that the support feet can be extended to a suitable position. The support feet 5 and the support bottom tube 1 form the support of the independent support frame, and the support feet 5 strengthen the stability of the support bottom tube 1 to prevent the support bottom tube 1 from tipping over.

[0040] See also Figure 4In one embodiment, a height adjustment device 6 is provided in the middle of the supporting bottom tube 1. The height adjustment device 6 utilizes the existing technical solution. For example, the height adjustment device 6 includes a hand crank 62, a first gear 64, a winch 63, a wire rope 61, a brake pin 66 and a housing 65. The housing 65 is fixedly installed in the middle of the supporting bottom tube 1. The hand crank 62 is arranged on the outside of the housing 65. One end of the hand crank 62 is fixedly connected to the first gear 64. The winch 63 includes a drum 632 and a second gear 631. The drum 632 is rotatably installed in the housing 65. One end of the drum 632 is fixedly installed with the second gear 631. The first gear 64 is meshed with the second gear 631. The first gear 64 drives the second gear 631 to rotate. The brake pin 66 is suspended on the outside of the housing 65. A through hole is arranged in the housing 65 near the first gear 64. The brake pin 66 can pass through the through hole and be stuck in the gap between adjacent gear teeth of the first gear 64. One end of the wire rope 61 is fixedly mounted on the drum 632 , and the other end is fixedly mounted in the sliding tube 2 .

[0041] When in use, the brake pin 66 is removed, and the hand crank 62 is manually rotated clockwise or counterclockwise, the first gear 64 rotates synchronously, the first gear 64 meshes with the second gear 631 to drive the drum 632 to rotate, thereby driving the wire rope 61 to rise or fall. During the lifting process, the sliding tube 2 moves up and down along the supporting bottom tube 1 through the pulling force of the wire rope 61. When stopping the lifting, the brake pin 66 is manually passed through the through hole and stuck in the gap between the adjacent gear teeth of the first gear 64, so that the first gear 64 cannot rotate, and the sliding tube 2 is fixed in the supporting bottom tube 1.

[0042] When in use, adjust the deployment angle of the support foot 5, and place the independent support frame stably under the mold. Adjust the positioning structure 3, let the positioning structure 3 pass through the positioning hole 11 and embed into the groove 21 of the sliding tube 2, and adjust the height adjustment device 6 to adjust the height of the sliding tube 2 so that the bearing plate contacts the mold. When the mold is higher from the ground and the sliding tube 2 rises, the baffle 22 contacts the positioning structure 3, and the positioning structure 3 prevents the baffle 22 from continuing to rise, thereby limiting the sliding tube 2 from continuing to move upward along the supporting bottom tube 1. Because the positioning structure 3 is set at a certain distance from the top of the supporting bottom tube 1, a certain length of the sliding tube 2 can be retained in the supporting bottom tube 1 to ensure that the sliding tube 2 does not separate from the supporting bottom tube 1 and avoid accidents.

[0043] In one embodiment, the positioning structure 3 includes a first nut 31 and a screw 32, and the first nut 31 is welded and installed outside the positioning hole 11. Preferably, the diameter of the positioning hole 11 is larger than the inner diameter of the first nut 31. The screw 32 is fixed to the first nut 31 by threaded engagement, and through the first nut 31, the screw 32 can enter or exit the positioning hole 11 by rotating the screw 32. The screw 32 can sequentially pass through the first nut 31, the positioning hole 11, and be inserted into the groove 21. When the sliding tube 2 rises to a certain distance, the baffle 22 contacts the screw 32, and the screw 32 limits the sliding tube 2 from continuing to rise.

[0044] See also Figure 3 In another embodiment, the positioning structure 3 is a spring positioning pin 33, which is installed on the outside of the supporting bottom tube 1, and the spring positioning pin 33 passes through the positioning hole 11 and is embedded in the groove 21. Specifically, the spring positioning pin 33 includes a second nut 34 and a pin body 35.

[0045] The second nut 34 is welded and installed on the outside of the supporting bottom tube 1, and the pin body 35 is provided with an external thread matching the internal thread of the second nut 34, and the pin body 35 is fixed to the second nut 34 by threaded engagement. The pin body 35 passes through the second nut 34, the positioning hole 11 and is inserted into the groove 21.

[0046] Furthermore, the pin body 35 includes a pin body 351, a stopper 352, an outer body 353, a pull ring 356 and a spring 354; the outer body 353 is provided with an external thread that matches the second nut 34, and the outer end and the inner end of the outer body 353 are both provided with openings 358; the pin body 351 is arranged in the outer body 353; a protrusion 355 is provided on the outer surface of the pin body 351, a stopper 352 is provided between the outer body 353 and the pin body 35, and the stopper 352 and the protrusion 355 are fixedly connected by a spring 354. The pin body 351 is provided with a through hole 357 at the outer end close to the outer body 353, and the pull ring 356 is installed in the through hole 357.

[0047] The pull ring 356 is pulled, and the pin body 351 moves toward the outer end of the outer body 353. The protrusion 355 on the pin body 351 squeezes the spring 354. The spring 354 is blocked by the stopper 352 and deforms, so that the pin body 351 can be separated from the groove 21. The pull ring 356 is released, the spring 354 is reset, and the pin body 351 returns to its original position, and the pin body 351 is embedded in the groove 21. Therefore, with the cooperation of the stopper 352, the protrusion 355 and the spring 354, the pin body 351 is retracted or extended into the openings 358 at the outer end and the inner end of the outer body 353, so that the pin body 351 is separated from or embedded in the groove 21.

[0048] In one embodiment, the sliding tube 2 is provided with two grooves 21, which are symmetrically arranged on the outside of the sliding tube 2; the baffle 22 covers the two grooves 21, two positioning holes 11 are arranged on the upper part of the supporting bottom tube 1, and two groups of positioning structures 3 are correspondingly arranged. With this structure, the two ends of the sliding tube 2 are symmetrically stressed, further enhancing the stability of the sliding tube 2.

[0049] Beneficial effects of the utility model:

[0050] The independent support frame is provided with a positioning structure 3 and a baffle 22. When the sliding tube 2 is about to rise to the limit, the positioning structure 3 cooperates with the baffle 22 to limit the sliding tube 2 from continuing to move upward along the supporting bottom tube 1. The sliding tube 2 retains a certain length in the supporting bottom tube 1, and the sliding tube 2 will not fall over, preventing accidents caused by negligence of the operating personnel.
