Description

Technical Field

[0001] The utility model patent relates to the field of steel cage manufacturing, specifically a steel bar forced alignment device for mechanical connection. Background Art

[0002] Large-diameter and extra-long pile foundation steel cages are increasingly being used in designs. Steel cages are generally transported in sections. After the processed steel cages are transported to the site, the main bars between the segmented steel cages are connected with threaded sleeves. However, the existing steel cages may be squeezed and deformed during transportation, resulting in a large distance between the main bar ends, making it impossible for the main bars at both ends to be aligned and inserted into the threaded sleeves. At this time, multiple workers can only forcibly adjust the position of the entire steel cage (such as forcibly offsetting the steel cage that needs to be docked toward the side where the main bar that cannot be docked is located) to reduce the distance between the two main bars and align them before they can be inserted into the threaded sleeves. The whole process is time-consuming and labor-intensive.

[0003] At the same time, the extrusion and deformation of the steel cage may also cause the position of the main reinforcement of the steel cage to be offset, resulting in the main reinforcement of the steel cage to be connected cannot be well aligned and inserted into the threaded sleeve together. When the main reinforcement of the two steel cages cannot be aligned, the construction workers are required to knock the steel bars with a hammer to force the main reinforcement of the two steel cages to align one by one. The construction process is more troublesome, and the main reinforcement is also damaged in the process of knocking. Because the main reinforcement is the load-bearing steel bar of the steel cage, it may affect the overall strength of the steel cage. Utility Model Content

[0004] The utility model is intended to provide a device for forcing the steel bars to be aligned mechanically, which is mainly used to solve the technical problem in the prior art that the steel cage is squeezed and deformed, resulting in the main bars being unable to be aligned, and the main bars are aligned by manually adjusting the position of the steel cage, which is time-consuming and labor-intensive.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A device for forcing reinforcement to close together for mechanical connection, comprising a main screw and a light rod arranged in parallel, wherein both ends of the light rod are fixedly connected to a limit plate, and the other end of the limit plate away from the light rod is rotatably connected to the end of the main screw, wherein the main screw comprises an upper thread and a lower thread with opposite spiral directions at the upper and lower ends, a hexagonal nut is provided on the middle fixed sleeve of the main screw, and a first connecting plate and a plurality of second connecting plates are provided on the sliding sleeve of the light rod, wherein the first connecting plate is connected to the upper thread, and the second connecting plate is threadably connected to the lower thread; a first screw is passed through the middle of the first connecting plate and is threadedly connected, a second screw arranged parallel to the first screw is passed through the middle of the second connecting plate and is threadedly connected, and a fixing device that can be fixedly connected to the main reinforcement is respectively installed at one end of the first screw and the second screw located on the same side, wherein the first screw is rotatably connected to the fixing device.

[0007] The working principle and beneficial effects of the utility model:

[0008] 1. Working principle: several single-section steel cages are assembled into a steel cage as a whole. During the assembly process, when it is necessary to combine the single-section steel cage with the assembled steel cage as a whole, here, in order to illustrate the use principle of this device, the main reinforcement of the single-section steel cage to be assembled is named A main reinforcement, and the main reinforcement of the assembled steel cage as a whole that needs to be connected with the single-section steel cage is called B main reinforcement; the use process of the entire mechanical connection steel bar forced closing device is as follows:

[0009] Use a wrench to clamp the hexagonal nut on the main screw (the hexagonal nut has six plate screwing surfaces, which are suitable for the commonly used hexagonal wrenches on the market, and the hexagonal wrench is matched with the plate screwing surface), which can drive the main screw to rotate, thereby driving the first connecting plate and the second connecting plate to move along the opposite upper and lower threads, adjusting the relative positions of several semicircular rings, and fixing the fixing device close to the second connecting plate with the B main reinforcement, positioning the entire steel bar forced alignment device for mechanical connection, and then fixing the fixing device close to the first connecting plate with the A main reinforcement, and then twisting the first screw, the first screw rotates relative to the fixing device, driving the matching fixing device to translate, thereby forcibly driving the A main reinforcement to move until the A main reinforcement is coaxially aligned with the B main reinforcement;

[0010] After the main reinforcement is aligned, clamp the hexagonal nut on the main screw with a wrench again and turn the wrench to drive the main screw to rotate, thereby driving the first connecting plate and the second connecting plate to move along the opposite upper and lower threads and approach each other, so that the fixing device fixes the A and B main reinforcements to face each other and insert them into the threaded sleeve.

[0011] 2. Beneficial effects:

[0012] 1. Compared with the prior art, this solution designs a steel bar forced alignment device, fixes the main bars on the two steel cages with two parts of the fixing device respectively, and then adjusts the relative positions of the two parts of the fixing device, so as to force the two misaligned main bars to align. Compared with the method of manually knocking to force the main bars to align, the steel bar forced alignment device of this solution is more labor-saving, and will not cause point-like impact injuries to the main bars of the steel cage, and there is no situation of causing strength damage to the main bars of the steel cage. More importantly, after the two main bars are aligned, the hexagonal nut on the main screw is rotated to drive the first and second connecting plates to move, thereby driving the first and second screws to move up and down, and then driving the two fixing devices to move closer to each other, and finally driving the two main bars to move closer to each other and insert them into the threaded sleeve. Compared with the technical solution of manually adjusting the positions of the two steel cages in the prior art, this solution uses tools to assist, which can not only align the main bars, but also bring the main bars together, which is more time-saving and labor-saving.

[0013] In summary, this solution solves the technical problem in the prior art that the main bars cannot be aligned due to the compression and deformation of the steel cage, and that it is time-consuming and labor-intensive to manually adjust the position of the steel cage to align the main bars.

[0014] Preferably, the fixing device comprises a semicircular ring with a U-shaped arrangement that can be elastically deformed, with ear plates fixedly connected at both ends of the ring, a through hole is provided on one ear plate, and a threaded hole coaxially arranged with the through hole is provided on the other ear plate, a third screw rod passes through the through hole and the threaded hole, the third screw rod is slidably connected to the through hole, the third screw rod is threadedly connected to the threaded hole, and a limiting handle for rotating the third screw rod is fixed at one end of the third screw rod close to the through hole. The limiting handle on each semicircular ring is rotated so that the threaded hole on the semicircular ring moves toward the through hole along the third screw rod, so that the ear plate drives the semicircular ring to tighten, clamps the peripheral surface of the main reinforcement, and realizes the function of clamping and fixing the main reinforcement.

[0015] Preferably, the first screw is rotatably connected to the semicircular ring, and a disc-shaped connecting block with a diameter smaller than the diameter of the first screw is integrally formed on the side of the first screw close to the semicircular ring, a buckle plate is rotatably sleeved on the connecting block, and an end of the connecting block away from the first screw is fixedly connected with a limit plate with a diameter larger than the diameter of the connecting block, the buckle plate is sleeved around the semicircular ring body, and both ends of the buckle plate are fixedly connected at the inner wall of the semicircular ring, and the limit plate is in contact with the outer circumferential surface of the semicircular ring.

[0016] In the present scheme, the end of the first screw is rotatably connected to the part of the buckle plate located on the outside of the semicircular ring. The specific rotational connection method is that the connecting block is inserted into the buckle plate and can rotate relative to the buckle plate, and then the end of the connecting block is upset to form a limit plate, or a limit plate is welded at the end of the connecting block, and the function of the limit plate is to jointly limit the connection block from separating from the buckle plate together with the end of the first screw. Then, the buckle plate is surrounded by the ring body of the semicircular ring, and then the two ends of the buckle plate are fixedly connected on the inner side of the semicircular ring, so that the buckle plate forms a ring shape and is fixed together with the semicircular ring.

[0017] When the first screw is rotated, the first screw will not drive the semicircular ring connected to it to rotate together. At the same time, during the rotation of the first screw, it is displaced relative to the first connecting plate, thereby driving the semicircular ring connected to the first screw to translate together, thereby achieving the effect of moving the A main reinforcement.

[0018] Preferably, the second screw is fixedly connected to the outer circumference of the semicircular ring. The advantage of this arrangement is that the semicircular ring on the second screw is first fixed to the main reinforcement B, the entire steel bar for mechanical connection can be forced to close the device for positioning, and then the position of the main reinforcement A can be better adjusted with the position of the main reinforcement B as a reference.

[0019] Preferably, the semicircular rings on the first, second and third screws are coaxially arranged.

[0020] Preferably, a plurality of anti-slip strips are fixedly connected to the inner side of the semicircular ring and are arranged at equal distances. The purpose of the anti-slip strips is to increase the friction between the semicircular ring and the main reinforcement, so that the semicircular ring can clamp the main reinforcement more stably.

[0021] Preferably, the anti-slip strip is in the shape of a triangular prism, one side of the anti-slip strip is perpendicular to the radial direction of the semicircular ring, and the length direction of the anti-slip strip is arranged parallel to the axis of the semicircular ring. The shape of the anti-slip strip is set to be a triangular prism, and the tip of the triangular prism is directed to the peripheral surface of the main rib, so as to increase the pressure on the contact surface between the anti-slip strip and the main rib, so that the semicircular ring can further clamp the main rib.

[0022] Preferably, a rotating handle is fixed to one end of the first screw rod and the second screw rod away from the fixing device. The rotating handle is provided to facilitate an operator to hold the rotating handle and rotate the first or second screw rod.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 As shown, a mechanically connected steel bar forced aligning device comprises a main screw rod 2 and a polished rod 1 arranged in parallel, the two ends of the polished rod 1 are fixedly connected to a limit plate 11, and the other end of the limit plate 11 away from the polished rod 1 is rotatably connected to the end of the main screw rod 2. Specifically, a support rod penetrating the limit plate 11 is welded to the end of the main screw rod 2, and one end of the support rod away from the second screw rod 42 is upset for limiting. Such an arrangement allows the second screw rod 42 to rotate relative to the limit plate 11, and overall, the arrangement of the limit plate 11 can ensure that the polished rod 1 and the second screw rod 42 are arranged in parallel;

[0031] The main screw 2 includes an upper thread and a lower thread with opposite spiral directions at the upper and lower ends. A hexagonal nut 21 is provided on the middle fixed sleeve of the main screw 2. A first connecting plate 31 and a plurality of second connecting plates 32 are provided on the sliding sleeve of the light rod 1, wherein the first connecting plate 31 is connected to the upper thread, and the second connecting plate 32 is threadedly connected to the lower thread; the hexagonal nut 21 on the main screw 2 is clamped with a wrench (the hexagonal nut 21 has six plate screwing surfaces, which are adapted to the commonly used hexagonal wrenches on the market, and the hexagonal wrench is matched with the plate screwing surfaces), and the wrench is turned to drive the main screw 2 to rotate, thereby driving the first connecting plate 31 and the second connecting plate 32 to move along the opposite upper and lower threads and approach each other. At the same time, a limit plate 11 is provided to ensure that the connecting plate will not fall out of the travel range of the light rod 1 and the second screw 42;

[0032] A first screw rod 41 passes through the middle of the first connecting plate 31 and is threadedly connected thereto, a second screw rod 42 which is arranged parallel to the first screw rod 41 passes through the middle of the second connecting plate 32 and is threadedly connected thereto, and a fixing device which can be fixedly connected to the main reinforcement is respectively installed at one end of the first screw rod 41 and the second screw rod 42 which are located on the same side, wherein the first screw rod 41 is rotatably connected to the fixing device, and the second screw rod 42 is fixedly connected thereto; a rotating handle 43 is fixed at one end of the first screw rod 41 and the second screw rod 42 which is away from the fixing device, so that the operator can hold the rotating handle 43 to rotate the first or second screw rod, and a first rotating hole 44 is provided in the middle of the rotating handle 43. When the handle 43 cannot be easily rotated, a long object such as a wooden stick or a thin steel bar can be inserted into the first rotating hole 44 to rotate the long object, and the handle 43 can be easily rotated by using the lever principle, thereby driving the first or second screw 42 to rotate.

[0033] like Figure 2 As shown, the fixing device includes a U-shaped semicircular ring 51 that can be elastically deformed, and ear plates 53 are fixedly connected at both ends of the ring. A through hole is opened on one ear plate 53, and a threaded hole coaxially arranged with the through hole is opened on the other ear plate 53. A third screw 54 passes through the through hole and the threaded hole. The third screw 54 is slidably connected to the through hole. The third screw 54 is threadedly connected to the threaded hole. A limiting handle 55 for rotating the third screw 54 is fixed at one end of the third screw 54 close to the through hole. The limiting handle 55 is fixed at one end of the third screw 54 close to the through hole. A second rotating hole 56 is provided in the middle of the handle 55. Referring to the principle of rotating the first or second screw rod, when the third screw rod 54 cannot be rotated, a long object (such as an iron rod) can be inserted into the second rotating hole 56 to rotate the third screw rod 54 using the lever principle; the limit handle 55 on each semicircular ring 51 is rotated to make the threaded hole on the semicircular ring 51 move toward the through hole along the third screw rod 54, so that the two ear plates 53 are close to each other, driving the semicircular ring 51 to tighten, clamping the circumference of the main reinforcement, and realizing the function of clamping and fixing the main reinforcement;

[0034] A number of equidistantly arranged anti-slip strips 52 are fixedly connected to the inner side of the semicircular ring 51. The anti-slip strips 52 are in the shape of a triangular prism. One side surface of the anti-slip strip 52 is perpendicular to the radial direction of the semicircular ring 51. The length direction of the anti-slip strip 52 is parallel to the axis of the semicircular ring 51. The shape of the anti-slip strip 52 is set to be a triangular prism, and the tip of the triangular prism is directed to the peripheral surface of the main reinforcement, thereby increasing the pressure on the contact surface between the anti-slip strip 52 and the main reinforcement, so that the semicircular ring 51 can further clamp the main reinforcement.

[0035] The first screw 41 is rotatably connected to the semicircular ring 51 in the fixing device, and a disc-shaped connecting block 61 with a diameter smaller than the diameter of the first screw 41 is integrally formed on the side of the first screw 41 close to the semicircular ring 51, and a long strip of buckle plate 7 is rotatably sleeved on the connecting block 61, and an end of the connecting block 61 away from the first screw 41 is fixedly connected to a limiting plate 62 with a diameter larger than the diameter of the connecting block 61, the buckle plate 7 is sleeved around the semicircular ring 51, and the two ends of the buckle plate 7 are fixedly connected at the inner wall of the semicircular ring 51, and the limiting plate 62 contacts the outer peripheral surface of the semicircular ring 51, that is, the end of the first screw 41 is rotatably connected to the part of the buckle plate 7 located outside the semicircular ring 51, and the specific rotational connection method is that the connecting block 61 is inserted into the buckle plate 7 and can rotate relative to the buckle plate 7 The limit plate 62 is used to limit the connection block 61 from being separated from the buckle plate 7 together with the end of the first screw rod 41. Then, the buckle plate 7 is wrapped around the ring body of the semicircular ring 51, and then the two ends of the buckle plate 7 are fixedly connected on the inner side of the semicircular ring 51, so that the buckle plate 7 forms a ring shape and is fixed together with the semicircular ring 51. When the first screw rod 41 is rotated, the first screw 41 will not drive the semicircular ring 51 connected thereto to rotate together. At the same time, during the rotation of the first screw 41, it is displaced relative to the first connecting plate 31, thereby driving the semicircular ring 51 connected to the first screw 41 to translate together, thereby achieving the effect of pulling and moving the main reinforcement.

[0036] The end of the second screw 42 is directly welded to the outer circumference of the semicircular ring 51 of the fixing device, and the semicircular rings on the first, second and third screws are coaxially arranged. When the semicircular ring 51 on the second screw 42 clamps the main reinforcement of the assembled steel cage, the entire steel bar forced alignment device for mechanical connection is positioned, and then the first connecting plate 31 is moved so that the semicircular ring 51 on the first screw 41 is sleeved to clamp the main reinforcement of another single-section steel cage, and the main reinforcement of the single-section steel cage is moved by twisting the first screw 41, so that the main reinforcements of the two steel cages are aligned.

[0037] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0038] Several single-section steel cages are assembled into a steel cage as a whole. During the assembly process, when it is necessary to combine the single-section steel cage with the assembled steel cage as a whole, here, in order to illustrate the use principle of the device, the main reinforcement of the single-section steel cage to be assembled is named A main reinforcement, and the main reinforcement of the assembled steel cage as a whole that needs to be connected with the single-section steel cage is called B main reinforcement; the use process of the entire mechanical connection steel bar forced closing device is as follows:

[0039] Use a wrench to clamp the hexagonal nut 21 on the main screw rod 2 (the hexagonal nut 21 has six plate screwing surfaces, which are suitable for the hexagonal wrench commonly used on the market, and the hexagonal wrench is matched with the plate screwing surface), which can drive the main screw rod 2 to rotate, thereby driving the first connecting plate 31 and the second connecting plate 32 to move along the opposite upper and lower threads, adjusting the relative positions of the three semicircular rings, and sleeve the two semicircular rings 51 close to the second connecting plate 32 on the B main reinforcement, and then screw the limit handle 55 so that the semicircular ring 51 clamps the B main reinforcement, and the entire reinforcement for mechanical connection is strengthened. The control device is positioned, and then the semicircular ring 51 close to the first connecting plate 31 is completely sleeved on the A main bar, and then the limit handle 55 is turned so that the semicircular ring 51 clamps the A main bar, and then the handle 43 is turned to rotate the first screw 41, driving the semicircular ring 51 matched therewith to move, thereby forcibly driving the A main bar to move until the A main bar is coaxially aligned with the B main bar; at the same time, the device can adjust the relative position with the main bar, pull the crooked main bar toward the required place, and finally make the main bars of the two steel cages coaxially aligned;

[0040] After the main reinforcement is aligned, clamp the hexagonal nut 21 on the main screw 2 with a wrench again, and turn the wrench to drive the main screw 2 to rotate, thereby driving the first connecting plate 31 and the second connecting plate 32 to move along the opposite upper and lower threads and approach each other, so that the fixing device fixes the A and B main reinforcements to be close to each other and inserted into the threaded sleeve.

[0041] Compared with the prior art method of using tools to forcibly knock the main bars to align the main bars, this solution solves the technical problem of the prior art that the misaligned main bars need to be manually aligned, which causes construction troubles. More importantly, after the two main bars are aligned, the hexagonal nut 21 on the main screw 2 is rotated to drive the first and second connecting plates 32 to move, thereby driving the first and second screws 42 to move up and down, and then driving the two fixing devices to move closer to each other, and finally driving the two main bars to move closer to each other and insert them into the threaded sleeve. Compared with the technical solution of manually adjusting the positions of the two steel cages in the prior art, this solution uses tools to assist, which can not only align the main bars, but also bring the main bars closer together, saving more time and effort.

[0042] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
