Description

Technical Field

[0001] This utility model relates to a temporary fixing device for tower cranes, belonging to the technical field of tower cranes. Background Technology

[0002] Currently, tower crane standard sections are connected using bearing plates, which significantly reduces the cost of tower crane installation and dismantling while improving construction efficiency and safety. In existing designs, the standard section must first be introduced, and the bearing plates must be placed on the standard section platform. After the standard section is introduced, the bearing plates are then manually moved to the connection point for installation. In the installation of ultra-large tower cranes, since the height of the standard section platform from the bearing plates is approximately 1.1-1.2 meters, and the bearing plates weigh over 60 kg, manually installing the bearing plates at the connection point is difficult and labor-intensive. Therefore, this invention designs a temporary bearing plate fixing device, where the bearing plates are initially installed on the standard section, avoiding manual handling of the bearing plates and improving the installation efficiency of the standard section. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a temporary fixing device for bearing tiles, which adopts an openable bearing tile structure to avoid manual handling of bearing tiles and improve the installation efficiency of standard sections.

[0004] This utility model is achieved through the following technical solution: a temporary fixing device for bearing plates, including a bearing plate pad, a pin column, a bearing plate, a connecting bolt, a limiting pin, and a stopper; the bearing plate pad is set on the cross web of a standard section, the pin column is set on the joint of the standard section, the bearing plate is installed on the pin column by the connecting bolt, the limiting pin is set on the bearing plate pad to fix the bearing plate in the open state on the bearing plate pad, and the stopper is set on another bearing plate pad to assist in fixing the position of the bearing plate.

[0005] The bearing plate has a bevel to limit the rotation of the bearing to a designated position.

[0006] The stopper includes a spring and a round steel bar, the spring being used to spring up the round steel bar to fix the bearing when it is rotated to a designated position.

[0007] The stopper includes a round steel bar with a ramp at the top. When the bearing plate rotates to the stopper, it contacts the ramp of the round steel bar and compresses the spring. When the bearing plate rotates to the designated position, the spring springs up and the round steel bar fixes the bearing plate.

[0008] The bearing plate is equipped with bearing plate stops to assist in the rotation of the bearing plate.

[0009] It also includes connecting screws for fixing the position of the bearing when it is closed.

[0010] The beneficial effects of this utility model are as follows: By welding a pin column to the side of the bearing plate, the bearing plate can rotate around the bolt, allowing it to be installed onto the joint before the standard section is installed. The use of a stopper consisting of a blocking pin and a round steel connecting spring secures the bearing plate in the designated position, preventing the bearing plate from swaying during standard section installation due to pre-installation, thus reducing installation time and improving the installation efficiency of the standard section.

[0020] like Figures 1 to 5 The illustrated temporary fixing device for bearing plates includes a bearing plate 1, a pin column 2, a bearing plate 3, a connecting bolt 4, a limiting pin 6, and a stopper 7. The bearing plate 1 is mounted on the cross web member 9 of the standard section, the pin column 2 is mounted on the joint of the standard section, the bearing plate 3 is mounted on the pin column 2 by the connecting bolt 4, the limiting pin 6 is mounted on the bearing plate 1 to fix the bearing plate 3 in the open state on the bearing plate 1, and the stopper 7 is mounted on another bearing plate 1 to assist in fixing the position of the bearing plate 3.

[0021] The bearing plate 1 has a bevel to limit the rotation of the bearing 3 to a designated position.

[0022] The stopper 7 includes a spring 7-1 and a round steel bar 7-2. The spring 7-1 is used to spring up the round steel bar 7-2 to fix the bearing 3 when the bearing 3 is rotated to a designated position.

[0023] The stopper 7 includes a ramp on the top of the round steel 7-2. When the bearing 3 rotates to the stopper 7, the bearing 3 contacts the ramp of the round steel 7-2 and compresses the spring 7-1. When the bearing 3 rotates to the designated position, the spring 7-1 springs up and the round steel 7-2 fixes the bearing 3.

[0024] The bearing 3 is equipped with a bearing stop 8 to assist the bearing rotation.

[0025] It also includes connecting screws 5, which are used to fix the position of the bearing 5 when the bearing is closed.

[0026] Method for fixing temporary fixing devices for roof tiles:

[0027] A bearing plate 1 is welded to a preset position on the standard section cross web 9. The bearing plate 1 has a bevel for positioning. The angle and position of the bevel are designed according to the rotation trajectory of the bearing 3 to limit the bearing 3 to rotate to a specified position in the open state.

[0028] Weld the pin column 2 at the corresponding position of the standard section joint to ensure that the bearing 3 can rotate around it.

[0029] The bearing plate 3 is composed of two arc-shaped steel plates. The side of each bearing plate 3 is mounted on the pin column 2 by connecting bolts 4, forming a hinged structure that can rotate around the bolts.

[0030] A retaining block 8 is welded to the outside of the retaining tile 3. The protruding direction of the retaining block is consistent with the rotation direction of the retaining tile 3, which is used by the operator to apply force to assist the rotation of the retaining tile 3.

[0031] A pin hole is made on the bearing pad 1 corresponding to the bearing position in the open state for inserting the limit pin 6; the stopper 7 is installed on another bearing pad 1, and its structure includes a spring 7-1 and a round steel 7-2. The top of the round steel 7-2 is provided with a slope. One end of the spring 7-1 is fixed on the bearing pad 1, and the other end is connected to the bottom of the round steel 7-2 to form a stopper structure that can be elastically reset.

[0032] Workflow of temporary fixing device for roof tiles:

[0033] Before installing the standard section, open and secure the bearing plate, remove connecting screw 5, and allow the bearing plate 3 to rotate. The operator applies force through the bearing plate stop 8 to rotate the bearing plate outward around the connecting bolt 4, thus opening the bearing plate structure.

[0034] When the bearing plate 3 rotates to the bevel position of the bearing plate pad 1, the limiting pin 6 is inserted through the pin hole of the bearing plate 3 and the bearing plate pad 1 and locked with a cotter pin to prevent the bearing plate from swinging during the lifting of the standard section.

[0035] When the other lobe of the retaining plate 3 rotates, the edge of the retaining plate 3 contacts the inclined plate of the round steel 7-2 of the stopper 7, pushing the round steel compression spring 7-1 to move downward; when the retaining plate 3 rotates to the designated position, the spring 7-1 bounces up the round steel 7-2, so that it is locked into the limiting groove of the retaining plate, thus completing the fixation of the double-lobed retaining plate.

[0036] Standard section introduction and bearing closure: After the standard section is introduced into place, first remove the limit pin 6, then pull down the lower screw of the stopper 7 to compress the spring 7-1 and move the round steel 7-2 down to release the obstruction of the bearing.

[0037] The bearing 3 rotates around the connecting bolt 4 under gravity or with manual assistance to reset and close to the outside of the standard section joint.

[0038] Finally, the two halves of the bearing are fixed with connecting screw 5 to complete the connection and installation of the standard section.

[0039] The positioning function of the bevel and the limiting pin: The bevel of the bearing pad 1 provides precise positioning for the bearing in the open state, and the limiting pin 6 forms a rigid fixation after insertion, preventing the bearing from shaking during the movement of the standard section.

[0040] The elastic locking mechanism of the stopper: The sloping design of the round steel 7-2 makes it easy to push the bearing down when it rotates, and the restoring force of the spring 7-1 makes the round steel automatically lock after the bearing is in place, realizing tool-free quick fixation.

[0041] The auxiliary operation of the bearing block: The bearing block 8 increases the force application point and reduces the labor intensity of the operator in rotating the bearing, which is especially suitable for bearings weighing more than 60kg.

[0042] With the above structural design, the bearing is initially installed on the standard section joint, eliminating the need for manual handling. During the standard section installation process, the bearing is temporarily fixed by limit pins and stoppers, avoiding the problem of having to climb 1.1-1.2m to carry the bearing during traditional manual installation, which significantly improves the installation efficiency of tower crane standard sections.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
