Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall thermal insulation, in particular to an attached wall connection device for construction equipment. Background Technique

[0002] Nowadays, the development direction of the construction industry is gradually towards prefabricated structures. At present, a considerable part of the exterior wall thermal insulation of prefabricated buildings has adopted non-removable thermal insulation boards, which can be cast together with the main body. At the same time, to meet the safety protection requirements, tower cranes, construction elevators, and climbing frames are also increasingly widely used in daily construction.

[0003] When installing construction equipment on a wall equipped with non-removable thermal insulation boards, it is not necessary to remove the thermal insulation boards at all the attachment parts. Only a hollow drill is used to precisely remove a hole with the same size as the corresponding structure in the connection device. However, in the existing attached wall connection device, the distance adjustment mechanism between the steel flat plate of the attached wall part and the thermal insulation board lacks flexibility, and it is often only adapted to thermal insulation boards of a single thickness, thus narrowing the scope of use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an attached wall connection device for construction equipment to solve the problem that the distance adjustment between the steel flat plate and the thermal insulation board of the existing attached wall connection device is not flexible, which limits its applicability to thermal insulation boards of different thicknesses and narrows the scope of use.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An attached wall connection device for construction equipment includes four externally threaded connecting rods arranged in a rectangular array, a steel flat plate on one side of the four externally threaded connecting rods, and further includes a rotation adjustment mechanism connected to one end of an externally threaded connecting rod, telescopic mechanisms respectively connected to three externally threaded connecting rods, second nuts respectively arranged on the rotation adjustment mechanism and the three telescopic mechanisms. The rotation adjustment mechanism and the three telescopic mechanisms are connected to the steel flat plate and one end of each of them penetrates and extends to one side of the steel flat plate, and the second nut abuts against one side of the steel flat plate.

[0006] Further, the rotation adjustment mechanism includes a first fixed sleeve with one end closed, a rotation cavity arranged inside the closed end of the first fixed sleeve, a rotation block arranged in the rotation cavity, an adjustment external threaded rod connected to one end of the rotation block and penetrating and extending to one side of the steel flat plate, an internal threaded sleeve threadedly matched with the adjustment external threaded rod and connected to one side of the steel flat plate at one end, two first sliders connected to the outer wall of the internal threaded sleeve at one end, and two first chutes arranged on the inner wall of the first fixed sleeve at intervals. The first slider is slidably matched with the first chute. One end of the internal threaded sleeve extends into the interior of the first fixed sleeve and is slidably matched with the inner wall of the first fixed sleeve. The closed end of the first fixed sleeve is connected to one end of an externally threaded connecting rod, and the adjustment external threaded rod is threadedly matched with a second nut.

[0007] Furthermore, the telescopic mechanism includes a second fixed sleeve with one end closed, a fixed external threaded rod connected to the inner wall of the closed end of the second fixed sleeve, a movable sleeve sleeved on the outer wall of the fixed external threaded rod and connected to one side of the steel flat plate at one end, two second sliders arranged at one end of the outer wall of the movable sleeve, and two second chutes arranged at intervals on the inner wall of the second fixed sleeve. The second sliders are slidably matched with the second chutes, and the fixed external threaded rod is threadedly matched with another second nut.

[0008] Furthermore, gaskets are provided on one side of both the first fixed sleeve and the second fixed sleeve, and the gaskets are sleeved on the outer wall of the external threaded connecting rod.

[0009] Furthermore, a first nut is threadedly matched with the end of the external threaded connecting rod away from the gasket.

[0010] Furthermore, a detachable connection assembly is provided on one side of the steel flat plate, and the detachable connection assembly is located between the four second nuts.

[0011] Furthermore, the detachable connection assembly includes an opening installation plate provided on one side of the steel flat plate, and two connecting ear plates connected to one side of the opening installation plate. The two connecting ear plates are arranged horizontally at intervals on one side of the opening installation plate, or the two connecting ear plates are arranged vertically at intervals on one side of the opening installation plate. The opening installation plate is connected to the steel flat plate by a plurality of bolts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When the device of the present utility model is connected to the external wall and the insulation board, through the cooperation of the four external threaded connecting rods, the rotation adjustment mechanism, the telescopic mechanism, the second nuts and the steel flat plate, by rotating the adjustment mechanism, the three telescopic mechanisms achieve synchronous telescopic actions, so as to complete the distance adjustment between the steel flat plate and the insulation board; this structure not only facilitates the flexible adjustment of the distance between the steel flat plate and insulation boards of different thicknesses, but also realizes simple operation and precise adjustment during the adjustment process, and improves the application range of the device.

[0024] Please refer to Figures 1-5, an attachment connection device for construction equipment, comprising four externally threaded connecting rods 4 arranged in a rectangular array, a steel flat plate 1 on one side of the four externally threaded connecting rods 4, further comprising a rotation adjustment mechanism 2 connected to one end of an externally threaded connecting rod 4, telescopic mechanisms 3 respectively connected to three externally threaded connecting rods 4, and second nuts 16 respectively arranged on the rotation adjustment mechanism 2 and the three telescopic mechanisms 3. The rotation adjustment mechanism 2 and the three telescopic mechanisms 3 are connected to the steel flat plate 1 and one end of each penetrates and extends to one side of the steel flat plate 1, and the second nuts 16 are abutted against one side of the steel flat plate 1; a thermal insulation board 23 is connected to one side of an external wall 22, a first installation hole for the externally threaded connecting rod 4 to pass through is opened on the external wall 22, and a second installation hole for the rotation adjustment mechanism 2 and the three telescopic mechanisms 3 to pass through is opened on the thermal insulation board 23, and the first installation hole and the second installation hole are adapted to each other; when the device is connected to the external wall 22 and the thermal insulation board 23, the four externally threaded connecting rods 4 respectively pass through the second installation hole and the first installation hole and extend to one side of the external wall 22, the rotation adjustment mechanism 2 and the three telescopic mechanisms 3 penetrate into the second installation hole and are abutted against one side of the external wall 22, according to the thickness of the thermal insulation board 23, the distance between the steel flat plate 1 and the thermal insulation board 23 is adjusted. By rotating and adjusting through the rotation adjustment mechanism 2, the steel flat plate 1 is driven to move horizontally, and the three telescopic mechanisms 3 synchronously expand and contract to complete the adjustment of the distance between the steel flat plate 1 and the thermal insulation board 23. After adjustment, the second nuts 16 are screwed on the rotation adjustment mechanism 2 and the three telescopic mechanisms 3 respectively to complete the fixation. This device is convenient for adjusting the distance between the steel flat plate 1 and the thermal insulation board 23 and enables the device to be applicable to thermal insulation boards 23 of different thicknesses. During adjustment, it has the characteristics of simple operation and precise adjustment, and improves the application range of the device.

[0025] The rotation adjustment mechanism 2 includes a first fixed sleeve 9 with one end closed, a rotation cavity 13 provided inside the closed end of the first fixed sleeve 9, a rotation block 14 provided inside the rotation cavity 13, an adjustment external threaded rod 15 connected to one end of the rotation block 14 and passing through and extending to one side of the steel flat plate 1, an internal threaded sleeve 12 threadedly engaged with the adjustment external threaded rod 15 and having one end connected to one side of the steel flat plate 1, two first sliders 11 connected to one end of the outer wall of the internal threaded sleeve 12, and two first chutes 10 provided on the inner wall of the first fixed sleeve 9 and arranged at intervals. The first sliders 11 are slidably engaged with the first chutes 10. One end of the internal threaded sleeve 12 extends into the interior of the first fixed sleeve 9 and is slidably engaged with the inner wall of the first fixed sleeve 9. The closed end of the first fixed sleeve 9 is connected to one end of an external threaded connecting rod 4. The adjustment external threaded rod 15 is threadedly engaged with a second nut 16. When adjusting the distance between the steel flat plate 1 and the heat preservation plate 23, rotate the adjustment external threaded rod 15. The rotation block 14 rotates within the rotation cavity 13, driving the internal threaded sleeve 12 to move on the adjustment external threaded rod 15. At the same time, the internal threaded sleeve 12 slides within the first fixed sleeve 9, and the first sliders 11 slide within the first chutes 10, playing a limiting role in the sliding of the internal threaded sleeve 12 within the first fixed sleeve 9 to prevent the internal threaded sleeve 12 from rotating within the first fixed sleeve 9. The internal threaded sleeve 12 drives the steel flat plate 1 to move towards or away from the heat preservation plate 23, completing the adjustment of the distance between the steel flat plate 1 and the heat preservation plate 23.

[0026] Four bolt holes 25 are arranged in a rectangular array on the steel flat plate 1. The adjustment external threaded rod 15 and three fixed external threaded rods 20 respectively pass through the four bolt holes 25 and can extend to one side of the steel flat plate 1.

[0027] The telescopic mechanism 3 includes a second fixed sleeve 17 with one end closed, a fixed external threaded rod 20 connected to the inner wall of the closed end of the second fixed sleeve 17, a movable sleeve 5 sleeved on the outer wall of the fixed external threaded rod 20 and having one end connected to one side of the steel flat plate 1, two second sliders 19 arranged at one end of the outer wall of the movable sleeve 5, and two second chutes 18 arranged at intervals on the inner wall of the second fixed sleeve 17. The second sliders 19 are slidably engaged with the second chutes 18. The fixed external threaded rod 20 is threadedly engaged with another second nut 16. When adjusting the distance between the steel flat plate 1 and the heat preservation plate 23, the movable sleeve 5 slides on the inner wall of the second fixed sleeve 17 and the outer wall of the fixed external threaded rod 20, and the second sliders 19 slide within the second chutes 18, facilitating the synchronous driving of the telescopic mechanism 3 to achieve telescoping during the adjustment process of the rotation adjustment mechanism 2.

[0028] Gaskets 21 are provided on one side of the first fixed sleeve 9 and the second fixed sleeve 17. The gaskets 21 are sleeved on the outer wall of the externally threaded connecting rod 4. The gasket 21 is placed in the second mounting hole to increase the contact area between the first fixed sleeve 9, the second fixed sleeve 17 and the outer wall 22, preventing wear on the end faces of the first fixed sleeve 9 and the second fixed sleeve 17.

[0029] One end of the externally threaded connecting rod 4 away from the gasket 21 is in threaded fit with a first nut 24. The first nut 24 is screwed onto the externally threaded connecting rod 4 passing through one side of the outer wall 22.

[0030] One side of the steel flat plate 1 is provided with a detachable connection assembly 6, and the detachable connection assembly 6 is located between four second nuts 16. The detachable connection assembly 6 includes an opening mounting plate 7 provided on one side of the steel flat plate 1 and two connecting ear plates 8 connected to one side of the opening mounting plate 7. The two connecting ear plates 8 are arranged horizontally at intervals on one side of the opening mounting plate 7, or the two connecting ear plates 8 are arranged vertically at intervals on one side of the opening mounting plate 7. The opening mounting plate 7 and the steel flat plate 1 are connected by a plurality of bolts. According to the usage requirements, the corresponding detachable connection assembly 6 can be conveniently replaced by connecting the opening mounting plate 7 and the steel flat plate 1 with a plurality of bolts. The tower crane and the construction elevator can be connected through the two connecting ear plates 8 arranged horizontally at intervals. The climbing frame can be connected through the two connecting ear plates 8 arranged vertically at intervals.

[0031] Working principle: When the device is connected to the exterior wall 22 and the thermal insulation board 23, the four external threaded connecting rods 4 respectively pass through the second mounting holes and the first mounting holes and extend to one side of the exterior wall 22. A first nut 24 is screwed onto the external threaded connecting rod 4 on one side of the exterior wall 22. The first fixing sleeve 9 and the three second fixing sleeves 17 are inserted into the second mounting holes and abut against one side of the exterior wall 22. According to the thickness of the thermal insulation board 23, the distance between the steel flat plate 1 and the thermal insulation board 23 is adjusted. The adjusting external threaded rod 15 is rotated, and the rotating block 14 rotates within the rotating cavity 13, driving the internal threaded sleeve 12 to move on the adjusting external threaded rod 15. At the same time, the internal threaded sleeve 12 slides within the first fixing sleeve 9. The first slider 11 slides within the first chute 10, playing a limiting role in the sliding of the internal threaded sleeve 12 within the first fixing sleeve 9 to prevent the internal threaded sleeve 12 from rotating within the first fixing sleeve 9. The internal threaded sleeve 12 drives the steel flat plate 1 to move towards or away from the thermal insulation board 23. The three telescopic mechanisms 3 synchronously expand and contract (specifically, the movable sleeve 5 slides on the inner wall of the second fixing sleeve 17 and the outer wall of the fixed external threaded rod 20, and the second slider 19 slides within the second chute 18), completing the adjustment of the distance between the steel flat plate 1 and the thermal insulation board 23. After adjustment, second nuts 16 are screwed onto the adjusting external threaded rod 15 and the three fixed external threaded rods 20 to complete the fixation, making the device convenient for adjusting the distance between the steel flat plate 1 and the thermal insulation board 23 and making the device applicable to thermal insulation boards 23 of different thicknesses. During adjustment, it has the characteristics of simple operation and precise adjustment, improving the application range of the device;

[0032] It can be connected to tower cranes and construction elevators through two connecting ear plates 8 arranged at intervals horizontally; it can be connected to climbing scaffolds through two connecting ear plates 8 arranged at intervals longitudinally.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
