Description

Technical Field

[0001] The utility model belongs to the technical field of tower cranes, and in particular relates to a tower crane foundation rain shielding device for safe hoisting of assembled buildings. Background Art

[0002] Tower cranes are a common type of lifting equipment, primarily used for vertical and horizontal material transportation and component installation in building construction. Because they rely on a suspended boom to lift loads, tower cranes exert a significant tipping moment and place high demands on the foundation's bearing capacity. Therefore, a stable foundation is essential for safe crane operation. Waterproofing is a crucial characteristic of tower cranes.

[0003] Chinese patent application No. 202222898526.9 discloses a tower crane foundation fixing rainproof device, including a precast concrete foundation, a first screw rod is fixedly connected to the top of the precast concrete foundation, a foundation base is placed on the top of the precast concrete foundation, and the foundation base is sleeved on the first screw rod, a nut is threadedly connected to the first screw rod, and the nut is squeezed on the foundation base, a rainproof plate is fixedly connected to the top of the rainproof plate, and a tower crane standard section is installed on the top of the rainproof plate by bolts, a second screw rod is threadedly connected to the four sides of the rainproof plate, and a protective cover is inserted into the inner side of the four sides of the foundation base.

[0004] In actual use, although the design of the above-mentioned flashing plate can protect the tower crane from rain, when the device is not in rain protection operation, the flashing plate cannot be quickly removed, which causes inconvenience to the staff's work, and the rainwater flowing along the flashing plate will contact the tower crane base. The accumulated rainwater continues to contact the tower crane base, which will also corrode the tower crane base, causing damage to the tower crane base, shortening the service life of the tower crane base, and failing to ensure the safety of construction. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to enable the device to realize the rapid erection and retraction of the rainproof device and solve the problem of inconvenience caused to the staff when the rainproof device is not needed.

[0006] In order to solve the above technical problems, the present invention proposes a tower crane foundation rain shielding device for safe hoisting of assembled buildings, wherein the tower crane foundation rain shielding device for safe hoisting of assembled buildings is installed on the tower crane, and the tower crane includes a tower crane standard section and a tower crane base, and the tower crane foundation rain shielding device for safe hoisting of assembled buildings includes a guide rail, a tarpaulin keel and a tarpaulin, wherein the guide rail is fixedly arranged around the tower crane standard section, a hinge is arranged between the tarpaulin keel and the guide rail, the tarpaulin is arranged on the tarpaulin keel, and a slide groove is further arranged around the tower crane standard section, the slide groove is arranged above the tarpaulin keel, a slider is arranged in the slide groove, a first pull ring is arranged on the tarpaulin keel, a second pull ring is arranged on the slider, a pull rod is arranged between the first pull ring and the second pull ring, and the design of the guide rail makes it possible to One end of the tarp is fixed on the guide rail, and the tarp can be quickly laid by pulling the tarp. The design of the tarp keel allows the tarp to be supported when blocking rain, thereby ensuring the efficiency of rain blocking. A hinge is set between the tarp keel and the guide rail, so that the tarp keel can rotate around the hinge, controlling the opening and closing angle of the tarp keel, and meeting the opening and contraction of the tarp keel, thereby meeting different working conditions. A slide groove is set around the standard section of the tower crane, and the slide groove is set above the tarp keel. A slider is set in the slide groove, so that the slider can slide in the slide groove. A first pull ring is set on the tarp keel, and a second pull ring is set on the slider. A pull rod is set between the first pull ring and the second pull ring, so that the opening and closing angle of the tarp keel can be controlled by controlling the position of the slider in the slide groove.

[0007] Furthermore, a lead screw is provided in the slide groove, the slider and the lead screw are threadedly connected, and a motor is provided at one end of the lead screw. The design of a lead screw provided in the slide groove, the slider and the lead screw are threadedly connected, and the motor is provided at one end of the lead screw makes it possible to control the rotation of the lead screw by controlling the forward rotation and flipping of the motor, thereby changing the position of the slider in the slide groove, and then stably and accurately controlling the opening and closing angle of the awning keel.

[0008] Furthermore, it also includes a limiting pin, and the awning keel is provided with a limiting hole corresponding to the limiting pin. The design of the limiting pin and the limiting hole on the awning keel can fix the awning on the awning keel through the one-to-one correspondence between the limiting pin and the limiting hole, thereby avoiding the displacement of the awning during the working process and ensuring its work efficiency.

[0009] Furthermore, a fixing clamp is provided on the inner side of the guide rail, which connects the guide rail and the standard section of the tower crane. The fixing clamp is fixed by a fixing bolt. The design of the fixing clamp and the fixing bolt enables the guide rail to be fixedly connected to the standard section of the tower crane, and the guide rail can be removed by rotating the fixing bolt, thereby facilitating the replacement of components in the device.

[0010] Furthermore, it includes an inner water-collecting slope and an outer water-collecting slope arranged on the tower crane base, the back of the inner water-collecting slope is fixedly connected to the tower crane base, a drain groove is arranged between the bottom of the inner water-collecting slope and the bottom of the outer water-collecting slope, a drain hole is arranged in the drain groove, the lower end of the drain hole is connected to a drain pipe, and the other end of the drain pipe is connected to a water reservoir, the design of the inner water-collecting slope and the outer water-collecting slope allows rainwater falling from the tarpaulin to enter the drain groove along the slope, the design of the drain hole in the drain groove allows rainwater gathered in the drain groove to enter the drain pipe arranged below the drain hole, and the rainwater enters the water reservoir along the drain pipe.

[0011] Furthermore, the tarpaulin is provided with a zipper. The design of the zipper on the tarpaulin enables the tarpaulin to be quickly assembled and disassembled, and the tarpaulin can be quickly replaced when the tarpaulin is damaged and needs to be replaced.

[0012] Furthermore, an upper limit block is provided at the upper end of the slide, and a lower limit block is provided at the lower end of the slide. The design of the upper limit block and the lower limit block restricts the movement of the slider in the slide, thereby avoiding damage to the device, extending the service life of the device, and ensuring that the device can operate correctly.

[0013] Furthermore, the beneficial effects of the present invention are as follows: when the device needs to perform rain-proof operation, it is only necessary to adjust the movement of the motor-controlled slider to open the tarpaulin keel; when the rain-proof operation is not required, there is no need to dismantle the device, and it is only necessary to adjust the movement of the motor-controlled slider to retract the tarpaulin keel, thereby avoiding the inconvenience caused by repeated disassembly and assembly. At the same time, the design of the internal water-collecting slope, external water-collecting slope, drainage groove, drainage hole, drainage pipe and water reservoir effectively prevents the accumulated rainwater from eroding the tower crane base, avoids damage to the tower crane base, prolongs the service life of the tower crane base, and ensures the safety of the device.
