Description

Technical Field

[0001] The invention relates to the technical field of reinforcement construction devices, in particular to a bridge steel structure reinforcement construction device. Background Art

[0002] The reinforcement of bridge steel structure is to strengthen the building by using carbon fiber, bonded steel and high-pressure grouting. It is a connection technology in the current earthquake-resistant reinforcement engineering of building structures, which uses structural adhesive to anchor the steel bars. When bonding steel to reinforce the bridge steel structure, it is necessary to apply glue to the surface of the bonded steel. Evenly applying the prepared glue on the working surface can increase the effect of the bonded steel reinforcement.

[0003] Although the existing reinforcement construction equipment is equipped with fixed components and operating platforms, it has obvious shortcomings. For example, in the invention with patent number CN114232521A, although the bottom of the fixed component of the equipment is equipped with pads for contacting the ground, these pads are fixed and cannot be adjusted. When the ground is uneven, this design defect will cause the pads to not fit completely to the ground, which may cause the device to shift or tilt during operation. In addition, due to the lack of anti-slip design on the bottom of the pads, the equipment is prone to slip during operation. At the same time, the fixed nature of the operating platform makes it difficult for users to carry a large number of tools or need to move to different work positions, which increases the complexity and inconvenience of mobile equipment.

A lower ball head 3311 is fixed, and the lower ball head 3311 is sleeved in the lower ball seat 335. The bottom of the lower ball seat 335 is fixed on the pad 336. A plurality of protrusions 337 are fixed on the bottom of the pad 336. An upper swivel ring 6 is provided on the connecting plate 5. A retaining ring 7 is clamped on the outer side of the upper swivel ring 6. A lower swivel ring 10 is provided at the bottom of the retaining ring 7. A plurality of balls 14 are provided between the lower swivel ring 10 and the upper swivel ring 6. A limit block 13 is provided next to each ball 14. A transmission gear 9 is meshed on the side of the inner ring of the upper swivel ring 6. A threaded rod 883 is meshed on the side of the transmission gear 9. The threaded rod 883 is fixed on the output end of the motor 881. A working platform 111 is provided on the upper swivel ring 6 above the threaded rod 883. The transmission gear 9 cooperates with the motor 881 and the threaded rod 883 to drive the upper swivel ring 6 to rotate, thereby rotating the working platform 111.

[0028] Furthermore, an upper groove 18 and a lower groove 19 are respectively provided at the bottom of the upper swivel ring 6 and the top of the lower swivel ring 10, and a second groove 17 is provided at the corner of the upper swivel ring 6, and a first groove 16 is provided on one side of the lower swivel ring 10. The upper groove 18 and the lower groove 19 are used to limit the circular motion of the ball 14 and the limit block 13 around the upper swivel ring 6 and the lower swivel ring 10, so that the rotation between the upper swivel ring 6 and the lower swivel ring 10 is smoother. The first groove 16 and the second groove 17 are used to embed the retaining ring 7.

[0029] Furthermore, a plurality of openings 15 are provided in a ring shape in the clamping ring 7 and on the lower rotating ring 10 , and a fixing bolt 12 is provided in each opening 15 . The fixing bolt 12 cooperates with the opening 15 provided on the lower rotating ring 10 to fix the clamping ring 7 .

[0030] Furthermore, a fixing block 882 is fixed between the motor 881 and the connecting plate 5, a fixing rod 884 is sleeved on the end of the threaded rod 883 away from the motor 881, a pin shaft 885 is sleeved inside the transmission gear 9, the fixing block 882 and the fixing rod 884 are used to fix the motor 881 and the threaded rod 883, and the pin shaft 885 is used to limit the transmission gear 9 to only perform rotational motion.

[0031] Furthermore, the working platform 111 is provided with a controller 112 for controlling the start and stop of the motor 881 , thereby controlling the rotation of the working platform 111 .

[0032] Furthermore, a lifting device 2 is provided at the bottom of the connecting plate 5 for lifting the working platform 111 to a height required by the user.

[0033] Furthermore, a plurality of moving wheels 11 are provided at the bottom of the base 4 to facilitate the movement of the device.

[0034] To summarize, when the device is in use, the supporting ball head 3312 is pushed downward by the stabilizing device 3, and the supporting ball head 3312 drives the supporting ball seat 3313 to move downward, thereby driving the pad 336 to move downward until the pad 336 is in contact with the ground, and then the device's own gravity is used to make the protrusion 337 insert into the ground to provide anti-slip force for the device. In the process of the pad 336 being in contact with the ground, the pad 336 tilts due to the potholes on the ground. At this time, the supporting ball head 3312 and the supporting ball seat 3313 rotate to cooperate with the inclination of the pad 336. The upper ball seat 334, the lower ball seat 335, the limiting support rod, the spring 332, the upper ball head 3310 and the lower ball head 3311 cooperate with the first limiting disk 333 to ensure that the pad 336 is in a horizontal state after leaving the ground, thereby avoiding the need to adjust the position of the pad 336 when it is used next time.

[0035] Then, the lifting device 2 is started to lift the working platform 111 to the required angle, and the motor 881 can be controlled to start through the controller 112. The motor 881 drives the threaded rod 883 to rotate, and the threaded rod 883 drives the transmission gear 9 to rotate. The transmission gear 9 drives the upper swivel 6 to rotate. The rotation of the upper swivel 6 drives the ball 14 to move, thereby reducing the friction between the upper swivel 6 and the lower swivel 10. Since the working platform 111 is fixed on the upper swivel 6, the working platform 111 rotates with the upper swivel 6 until it reaches the required position. If the upper swivel 6 or the lower swivel 10 needs to be inspected, only the fixing bolt 12 needs to be removed, and then the retaining ring 7 can be removed, and finally the upper swivel 6 can be inspected.

[0036] The overall operation process is to first fit the pad 336 to the ground through the stabilizing device 3, then lift the working platform 111 to the required height through the lifting device 2, and then control the rotation of the working platform 111 through the controller 112.

[0037] It is worth noting that the entire device is controlled by a general control device. Since the devices matched with the control device are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
