[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a mobile municipal landscape bridge construction hanging basket. Background Art

[0002] A hanging basket is a basket-type workbench welded with steel sections, suitable for high-altitude construction operations. When welding steel bars and installing formwork for anti-collision guardrails in bridge projects, operators cannot work within the beam body, and an operating platform needs to be set up for construction.

[0003] The existing patent authorization number is: CN215164809U, which discloses a movable construction hanging basket for municipal bridges, including a movable counterweight platform set on the bridge deck of the municipal bridge, an adjustable construction hanging frame set on the outside of the municipal bridge, and a connecting component set between the movable counterweight platform and the adjustable construction hanging frame for connecting the movable counterweight platform and the adjustable construction hanging frame. By setting up a movable counterweight platform, the hanging basket is convenient for directly moving the construction hanging basket, thereby reducing the erection time of the construction hanging basket. After analyzing the hanging basket, it can be known that during use, the lifting and translation of the construction platform cannot be adjusted according to the real-time construction position of the bridge, and the degree of automation is low. Moreover, the selection of the construction platform cannot be changed and adjusted according to the requirements of the construction personnel and quantity, and the overall scope of application is limited;

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a mobile municipal landscape bridge construction hanging basket. Utility Model Content

[0005] The purpose of the utility model is to provide a mobile municipal landscape bridge construction hanging basket to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mobile municipal landscape bridge construction hanging basket, including a construction platform; a lifting mechanism is detachably installed on one side of the construction platform, and a mobile positioning bracket that moves along the bridge is connected to the top of the lifting mechanism. The construction platform is placed on the outside of the bridge, and the horizontal and vertical positions of the construction platform are adjusted under the control of the lifting mechanism and the mobile positioning bracket, so as to carry out construction at different positions on the outside of the bridge. The mobile positioning bracket includes a mobile gravity base frame with a rectangular structure, and mobile wheels for controlling the movement of the mobile gravity base frame are rollingly provided at the four corners of the bottom of the mobile gravity base frame. A gravity block is detachably installed on one side of the top of the mobile gravity base frame. The gravity block is provided to maintain balance on both sides when the construction platform is placed on the outside of the bridge and the mobile gravity base frame is placed on the inside of the bridge. Four columns are fixedly installed at the four corners of the top of the mobile gravity base frame. A rectangular horizontal ladder extending to the outside of the bridge is commonly installed at the top, and the bottom of the horizontal ladder extending to the outside of the bridge is connected to the lifting mechanism, which includes lifting rods fixedly installed on both sides of the bottom end of the horizontal ladder, and a group of U-shaped lifting sleeves are installed on the lower sides of the lifting rods on both sides. A fixed rod is fixedly installed at the upper opening of the lifting sleeve, and a piston rod is connected to the middle part of the top of the fixed rod. The top of the piston rod is connected to a cylinder whose end is fixed in the middle part of the bottom of the horizontal ladder. That is, the cylinder is started to drive the piston rod to rise and fall, and then drive the fixed rod to control the lifting sleeve to extend and retract along the lifting rod. The construction platform is detachably installed on the lower side wall of the lifting sleeve. While controlling the lifting of the lifting sleeve, the construction height of the construction platform is adjusted. That is, the movement of the mobile gravity base is coordinated with the lifting of the lifting sleeve to automatically control the horizontal and vertical adjustment of the construction platform, thereby realizing mobile construction on the outside of the bridge.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] See also Figure 1-Figure 4The lifting mechanism is connected to the lifting platform 10 so that the lifting platform 10 can move along the bridge, and the lifting platform 10 can be placed on the outside of the bridge. Under the control of the lifting mechanism and the moving positioning bracket, the horizontal and vertical positions of the construction platform 10 can be adjusted to carry out construction at different positions on the outside of the bridge. The moving positioning bracket includes a moving gravity base frame 11 with a rectangular structure. The four corners of the bottom of the moving gravity base frame 11 are rolled with moving wheels 12 for controlling the movement of the moving gravity base frame 11. A gravity block 17 is detachably installed on one side of the top of the moving gravity base frame 11. The gravity block 17 is set to maintain the balance on both sides when the construction platform 10 is placed on the outside of the bridge and the moving gravity base frame 11 is placed on the inside of the bridge. Four columns 14 are fixedly installed at the four corners of the top of the moving gravity base frame 11, and rectangular horizontal climbing columns 14 extending to the outside of the bridge are installed on the top of the columns 14. The ladder 16 extends to the bottom of the horizontal ladder 16 outside the bridge and is connected to the lifting mechanism. The lifting mechanism includes lifting rods 19 fixedly installed on both sides of the bottom of the horizontal ladder 16 end, and a group of U-shaped lifting sleeves 20 are sheathed on the lower sides of the lifting rods 19 on both sides. A fixed rod 21 is fixedly installed at the upper opening of the lifting sleeve 20, and a piston rod 22 is connected to the top middle part of the fixed rod 21. The top of the piston rod 22 is connected to a cylinder 23 whose end is fixed to the bottom middle part of the horizontal ladder 16. That is, the cylinder 23 is started to drive the piston rod 22 to rise and fall, and then drive the fixed rod 21 to control the lifting sleeve 20 to extend and retract along the lifting rod 19. The construction platform 10 is detachably installed on the lower side wall of the lifting sleeve 20. While controlling the lifting of the lifting sleeve 20, the construction height of the construction platform 10 is adjusted. That is, the movement of the mobile gravity base frame 11 is coordinated with the lifting of the lifting sleeve 20 to automatically control the lateral and longitudinal adjustment of the construction platform 10, thereby realizing mobile construction on the outside of the bridge.

[0019] In the embodiment of the present invention, the two groups of columns 14 near one side of the lifting rod 19 are spaced apart from the two groups of lifting rods 19. During the actual construction process, the two groups of columns 14 and the two groups of lifting rods 19 are respectively placed on both sides of the bridge eaves; two triangular-structured handrails 18 are symmetrically installed on both sides of the top of the horizontal ladder 16, and the lower side of the end of the horizontal ladder 16 away from the lifting rod 19 is connected to the side ladder 15, and the bottom end of the side ladder 15 is fixed to the top of the mobile gravity base 11. The construction workers climb along the side ladder 15 and the horizontal ladder 16 to the outer end of the horizontal ladder 16, and then initially move the construction platform 10 to the highest point. At this time, the construction workers transfer between the construction platform 10 and the horizontal ladder 16, thereby realizing the smooth and safe transfer of the construction workers.

[0020] It should be noted that, since the lifting sleeve 20 is configured as a U-shaped structure, the inner side of the lifting sleeve 20 is configured as an opening, so that the construction workers placed on the construction platform 10 can directly perform construction on the outer side of the bridge;

[0021] A U-shaped guardrail 26 is installed on the top of the construction platform 10. The open end of the guardrail 26 is arranged toward the side of the lifting sleeve 20. That is, the guardrail 26 provides safety protection for the construction workers on the construction platform 10 while not blocking or hindering the construction outside the bridge.

[0022] The side wall of the mobile gravity chassis 11 is provided with a drive system 13, which is mechanically connected to the moving wheel 12. The drive system 13 is automatically controlled to drive the movement and stop of the moving wheel 12. The drive system 13 includes the following main components:

[0023] Power source: Usually an engine or electric motor, responsible for generating power.

[0024] Transmission: includes clutch, transmission, drive shaft, etc., used to transmit the power generated by the power source to the wheels.

[0025] Differential: Allows the wheels on both sides to rotate at different speeds when the vehicle turns, ensuring smooth driving of the vehicle.

[0026] Drive shaft: connects the transmission device and the moving wheel 12, transmits power to the moving wheel 12, and drives the moving wheel 12 to run.

[0027] The specific principle of the driving system 13 driving the moving wheel 12 to operate belongs to conventional structural design, so it will not be described in detail here.

[0028] In one embodiment of the present invention, a plurality of bayonet pins 24 are evenly installed on the side wall of the construction platform 10 facing the lifting sleeve 20, and a slot 25 is provided on the lower side wall of the lifting sleeve 20 corresponding to the end of the bayonet pin 24. The bayonet pin 24 is engaged with the slot 25 to realize a detachable connection between the construction platform 10 and the lifting sleeve 20. In this way, a construction platform 10 of appropriate size is used according to the requirements of bridge construction. At the same time, in order to maintain the balance between the mobile gravity base frame 11 and the construction platform 10 after the construction platform 10 is replaced, the gravity block 17 can be adjusted as needed. A base is installed at the bottom of the gravity block 17, and a plurality of bolt holes are evenly provided on the base. The bolt holes are threadedly connected to the mobile gravity base frame 11 through fastening bolts to maintain the detachable connection between the gravity block 17 and the mobile gravity base frame 11.

[0029] As a preferred embodiment of the present invention, a limiting cap is provided at the bottom end of the lifting rod 19 placed inside the lifting sleeve 20, so that the lifting sleeve 20 can be detached from the bottom of the lifting rod 19 when the cylinder 23 adjusts the height of the lifting sleeve 20. The cylinder 23 can also be set with a suitable stroke to control the maximum distance of the piston rod 22 falling while still keeping the lifting sleeve 20 mounted on the lifting rod 19. The specific choice depends on the actual situation.

[0030] The working principle of the present invention is as follows: in the idle space of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in a sequential working order between the electrical components. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, according to the requirements of the construction outside the bridge, a construction platform 10 of appropriate size is selected and installed on the lower side of the lifting sleeve 20 through the bayonet 24 and the slot 25, and the balance between the construction platform 10 and the mobile gravity chassis 11 is measured. A gravity block 17 of appropriate weight is installed on the top of the mobile gravity base 11, and then the lifting rod 19 and the column 14 are placed on the inner and outer sides of the bridge eaves respectively. Then the construction workers enter the construction platform 10 along the side ladder 15 and the horizontal ladder 16, and then operate the automatic control drive system 13 and the cylinder 23. When the drive system 13 is running, it drives the moving wheel 12 to control the mobile gravity base 11 to move along the length direction of the bridge. When the cylinder 23 is running, it drives the piston rod 22 to control the lifting sleeve 20 to move up and down, so as to adjust the horizontal and vertical positions of the construction platform 10 and carry out construction on the outside of the bridge.

[0031] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
