Description

Technical Field

[0001] This utility model belongs to the technical field of positioning devices, specifically a hoisting and positioning device for a wooden beam formwork. Background Technology

[0002] Wooden beam formwork is a formwork system commonly used in concrete structure pouring during building construction. During construction, the wooden beam formwork needs to be hoisted as a whole to be placed in a designated position. The current common hoisting method is to use lifting equipment to lift the wooden beam formwork and then manually operate the traction rope to adjust its position and posture in an attempt to achieve precise positioning.

[0003] However, due to the large size and weight of the wooden beam formwork, it is difficult to achieve rapid and stable position adjustment by simply pulling the traction rope manually. Especially when working at heights, the operator's control accuracy over the traction rope will be greatly affected, which can easily lead to excessive swaying of the formwork. This not only increases the difficulty of positioning but may also cause safety accidents. Therefore, an overall hoisting and positioning device for the wooden beam formwork is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a whole-body hoisting and positioning device for wooden beam formwork is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The overall hoisting and positioning device for wooden beam platform formwork of this utility model includes a limiting frame and a fixing plate; a positioning plate is fixedly connected to one side of the limiting frame, and the other end of the positioning plate is inserted into a positioning groove opened on one side of the fixing plate; an adjusting block is installed on the limiting frame; a positioning component is provided on the fixing plate, and the positioning component is used to move and position the fixing plate.

[0006] The fixed plate is equipped with a positioning mechanism, which includes a support groove on the top of the fixed plate, a support plate slidably connected in the support groove, traction rings fixedly connected to both sides of the support plate, and through holes communicating with the support groove on both sides of the fixed plate. A traction rope is wound around the outer wall of the traction ring. The positioning mechanism facilitates the positioning and guidance of the overall hoisting of the wooden beam platform formwork in conjunction with the limiting frame and the fixed plate, thereby improving the safety during the hoisting process.

[0007] Preferably, the inner bottom wall of the support groove is provided with an auxiliary groove, and the inner side wall of the auxiliary groove is rotatably connected to an auxiliary roller via a rotating shaft. By setting the auxiliary groove and the auxiliary roller, the resistance when the support plate moves can be reduced, and the labor consumption can be reduced.

[0008] Preferably, the positioning element includes a mounting groove formed at the bottom of the fixing plate, and a first electric telescopic rod is fixedly connected to the inner wall of the mounting groove. The output end of the first electric telescopic rod extends out of the mounting groove and is fixedly connected to the limiting frame. The positioning element is formed by the arrangement of the first electric telescopic rod and the mounting groove.

[0009] Preferably, a guide plate is fixedly connected to the inner bottom wall of the limiting frame. The guide plate is inclined and can assist in guiding and correcting the wooden beam formwork.

[0010] Preferably, the top of the limiting frame is provided with an adjustment groove, and a second electric telescopic rod is fixedly connected to the inner bottom wall of the adjustment groove. The output end of the second electric telescopic rod extends out of the adjustment groove and is fixedly connected to the bottom of the adjustment block. With the setting of the second electric telescopic rod and the adjustment groove, the position of the adjustment block can be easily adjusted so that the device can be adapted to the positioning of wooden beam formwork of different heights.

[0011] Preferably, a lifting ring is fixedly connected to one side of the limiting frame, and a maintenance groove communicating with the adjustment groove is opened on one side of the limiting frame. The lifting ring facilitates the hoisting of the device to the place of use after assembly.

[0012] Preferably, the bottom of the adjusting block is provided with anti-slip protrusions to increase friction, and the top of the support plate is provided with anti-slip textures to increase friction.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides an overall hoisting and positioning device for wooden beam formwork. By pulling the traction rope, the support plate is moved in conjunction with the traction ring, which in turn moves the wooden beam formwork placed on the support plate. Two limiting frames are placed on both sides of the already installed wooden beam formwork. The first electric telescopic rod is activated, and the two limiting frames are aligned with one side of the wooden beam formwork. The second electric telescopic rod is activated, so that the bottom of the adjusting block is aligned with the top of the wooden beam formwork. The other wooden beam formwork is lifted by a crane and placed on the support plate. Pulling the traction rope on the traction ring near the first wooden beam formwork moves the support plate, which assists in supporting the wooden beam formwork and prevents it from shaking significantly, until one end of the second wooden beam formwork abuts against one end of the first wooden beam formwork, thus fixing the two wooden beam formwork together.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides an overall hoisting and positioning device for wooden beam formwork, including two L-shaped limiting frames 1 and a rectangular fixing plate 2, with the fixing plate 2 located between the two limiting frames 1;

[0025] Five equally spaced rectangular positioning plates 3 are fixedly connected to one side of the limiting frame 1. The other end of the positioning plate 3 is inserted into the rectangular positioning groove 4 opened on one side of the fixed plate 2. The positioning plates 3 and the positioning groove 4 enable the two limiting frames 1 to cooperate to support the fixed plate 2.

[0026] An adjusting block 5 is installed on the limiting frame 1. The bottom of the adjusting block 5 is provided with anti-slip protrusions to improve friction. The adjusting block 5 can be fixed to the limiting frame 1 by welding or can be installed on the limiting frame 1 by adjusting its position.

[0027] The limiting frame 1 is provided with an adjustment groove 11 at the top, and a second electric telescopic rod 12 is fixedly connected to the inner bottom wall of the adjustment groove 11. The output end of the second electric telescopic rod 12 extends out of the adjustment groove 11 and is fixedly connected to the bottom of the adjustment block 5.

[0028] The second electric telescopic rod 12 and the adjustment groove 11 make it easy to adjust the position of the adjustment block 5 so that the device can be adapted to the positioning of wooden beam formwork of different heights.

[0029] The above describes the adjustment and fixing method of the adjusting block 5. The adjusting block 5 is used in conjunction with two limiting brackets 1 and a fixing plate 2 to facilitate its placement on the completed wooden beam formwork.

[0030] A lifting ring 13 is fixedly connected to one side of the limiting frame 1. A maintenance groove 14 communicating with the adjustment groove 11 is opened on one side of the limiting frame 1. The lifting ring 13 makes it easy to lift the device to the place of use after assembly. The maintenance groove 14 makes it easy to install and maintain the second electric telescopic rod 12.

[0031] A guide plate is fixedly connected to the inner bottom wall of the limiting frame 1. The guide plate is inclined and can assist in guiding and correcting the wooden beam formwork.

[0032] The fixed plate 2 is provided with a positioning element, which is used to move and position the fixed plate 2.

[0033] The positioning component includes a mounting groove 9 formed at the bottom of the fixed plate 2. A first electric telescopic rod 10 is fixedly connected to the inner wall of the mounting groove 9. The output end of the first electric telescopic rod 10 extends out of the mounting groove 9 and is fixedly connected to the limit frame 1. The positioning component is formed by the arrangement of the first electric telescopic rod 10 and the mounting groove 9.

[0034] The fixed plate 2 is provided with a positioning mechanism 6. The positioning mechanism 6 includes a rectangular support groove 61 opened on the top of the fixed plate 2. A rectangular support plate 62 is slidably connected in the support groove 61. The top of the support plate 62 is provided with anti-slip texture to improve friction.

[0035] The sliding support plate 62 drives the wooden beam formwork placed on the support plate 62 to move closer to the already installed wooden beam formwork.

[0036] An auxiliary groove 8 is provided on the inner bottom wall of the support groove 61, and an auxiliary roller 7 is rotatably connected to the inner side wall of the auxiliary groove 8 via a rotating shaft.

[0037] By using the auxiliary groove 8 and the auxiliary roller 7, the bottom of the support plate 62 does not directly contact the inner bottom wall of the support groove 61, but is supported by the rotating auxiliary roller 7. This reduces the resistance when the support plate 62 moves and reduces manpower consumption.

[0038] A circular traction ring 63 is fixedly connected to both sides of the support plate 62. Both sides of the fixing plate 2 are provided with through holes 64 that communicate with the support groove 61. A traction rope 65 is wrapped around the outer wall of the traction ring 63.

[0039] By pulling the traction rope 65, the support plate 62 is moved in conjunction with the traction ring 63, thereby moving the wooden beam formwork placed on the support plate 62.

[0040] The positioning mechanism 6 facilitates the positioning and guidance of the entire wooden beam platform formwork during hoisting, in conjunction with the limiting frame 1 and the fixing plate 2, thereby improving safety during the hoisting process.

[0041] Based on the above structure, the present invention includes the following implementation process:

[0042] First, a wooden beam formwork is hoisted to the installation location using a crane and then installed and fixed, using this wooden beam formwork as a base point;

[0043] First, perform a simple assembly of the device, that is, place the fixing plate 2 between the two limiting frames 1, insert the positioning plate 3 into the positioning groove 4, and weld the outer end of the second electric telescopic rod 12 to the side of the limiting frame 1 near the fixing plate 2.

[0044] Tie one end of the hoisting rope to the hoisting ring 13, and use the hoist to hoist the device to the side of the wooden beam formwork that has been installed and fixed. Untie the hoisting rope from the hoisting ring 13 and connect the first electric telescopic rod 10 and the second electric telescopic rod 12 to the power supply through the external power line.

[0045] Place the two limiting brackets 1 on both sides of the already installed wooden beam formwork, and make the top of the fixing plate 2 abut against the bottom of the wooden beam formwork.

[0046] Based on the width and height of the already installed and fixed wooden beam formwork, the first electric telescopic rod 10 is activated to drive the two limit frames 1 to approach the wooden beam formwork until the two limit frames 1 are in contact with one side of the already installed wooden beam formwork.

[0047] The second electric telescopic rod 12 is activated to drive the adjusting block 5 to rise and fall, so that the bottom of the adjusting block 5 fits against the top of the wooden beam formwork that has been installed and fixed. The two limit frames 1, the two adjusting blocks 5 and the fixing plate 2 cooperate to clamp and sleeve the device on the outside of the wooden beam formwork that has been installed and fixed.

[0048] At this time, the limiting frame 1 and the fixing plate 2 extend mostly outside the wooden beam formwork that has been installed and fixed, so as to provide auxiliary support and movement assistance for the subsequent hoisting of the wooden beam formwork.

[0049] At this point, another wooden beam formwork can be lifted by a crane, and after reaching a height roughly corresponding to the already installed wooden beam formwork, the second wooden beam formwork can be lifted onto the support plate 62, but the crane will not release the lifting of the wooden beam formwork.

[0050] At this time, the traction rope 65 on the traction ring 63 near the first wooden beam formwork can be pulled to move the support plate 62. During this process, the support plate 62 assists in supporting the wooden beam formwork and prevents the wooden beam formwork from shaking too much.

[0051] As the second wooden beam formwork approaches the first wooden beam formwork, the second wooden beam formwork will come into contact with the two guide plates, and the tilted guide plates will correct any tilting of the wooden beam formwork and center it in the correct position.

[0052] Once one end of the second wooden beam formwork abuts against one end of the first wooden beam formwork, the installation and fixing between the second and first wooden beam formwork can be carried out.

[0053] After installation, restart the first electric telescopic rod 10 and the second electric telescopic rod 12 respectively, so that the limit frame 1 is away from the second wooden beam platform. Then, the device can be moved manually or by pulling the traction rope 65, so that the device can be moved from the first wooden beam platform to the second wooden beam platform.

[0054] The above steps can be repeated to clamp and mount the device on the outside of the second wooden beam formwork for hoisting and positioning the third wooden beam formwork. Repeat the above steps until all the wooden beam formwork is hoisted and installed. This device is suitable for hoisting and positioning multiple wooden beam formwork sections over long distances.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
