Description

Technical Field

[0001] The utility model belongs to the technical field of engineering cap beams, and in particular relates to a cap beam maintenance support structure. Background Art

[0002] The cap beam refers to the beam installed on the top of the frame pile pier to support, distribute and transfer the load of the superstructure. It is also called the cap beam. The reinforced concrete or lightly reinforced concrete beam installed on the pier (platform) or on the pile row mainly supports the superstructure of the bridge and transfers all the loads to the lower structure.

[0003] Problems with existing technologies:

[0004] At present, in order to ensure safety during the inspection of the cap beam, it is necessary to support it during inspection to prevent accidental collapse. The existing cap beam support structures are mostly overlapped support frames, which need to be overlapped each time they are used. The support frames have many parts, and the overlap is time-consuming and labor-intensive. In addition, it is also troublesome to adjust the position and height of the support frames. At the same time, the cap beam is generally at a high place and is not convenient for observation. When supporting it, there will be a height difference on both sides of the cap beam that cracks in the middle, which can easily lead to only supporting the lower side and ignoring the other side. There are also situations where the supporting force is too large, causing the originally qualified cap beam to be destroyed by the supporting force. Utility Model Content

[0027] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0028] like Figure 1 - Figure 5 As shown, a cap beam maintenance support structure comprises: a movable base plate 1, a lifting support column 2 is fixedly connected to the top of the movable base plate 1, a lifting support platform 3 is arranged on one side of the lifting support column 2, the lifting support platform 3 is slidably connected to the lifting support column 2, and a movable roller 4 is fixedly connected to the bottom of the movable base plate 1;

[0029] A support plate is fixedly connected to the upper end of the lifting support column 2, and a lifting drive assembly 9 is arranged on the support plate. The lifting drive assembly 9 includes a driving motor 12, and the output end of the driving motor 12 is fixedly connected to a driving worm 11, and a driving connecting shaft 15 is laterally arranged above the driving worm 11. The driving connecting shaft 15 is fixedly connected to a driving turbine 13 at a position corresponding to the driving worm 11. The driving motor 12 is meshed and connected with the driving turbine 13. A driving toothed disc 14 is arranged on the driving connecting shaft 15, and a lifting chain 10 is arranged on the two driving toothed discs 14. A counterweight balancing block 16 is fixedly connected to one end of the lifting chain 10 close to the driving motor 12, and the other end of the lifting chain 10 is fixedly connected to the lifting support platform 3;

[0030] The lifting support platform 3 includes a lifting drive assembly 9 , on which a pressure contact plate 5 is arranged, and inside of the lifting drive assembly 9 a pressure sensing assembly is arranged.

[0031] The entire device is moved by moving the movable substrate 1, and the movable roller 4 under the movable substrate 1 can facilitate its movement;

[0032] When support is needed, the worm 11 is driven to rotate by starting the driving motor 12, and the driving worm 11 drives the driving turbine 13 to rotate. The driving turbine 13 is fixedly connected to the driving connecting shaft 15 and will also rotate. The driving gear plate 14 on the driving connecting shaft 15 can drive the lifting chain 10 to transmit, so that the position of the counterweight balance block 16 and the lifting support platform 3 is changed, so that the lifting support platform 3 can move to support the cap beam;

[0033] When the lifting support platform 3 supports the cap beam, the pressure contact plate 5 on the lifting drive assembly 9 first contacts the cap beam. When the cap beam contacts the pressure contact plate 5 and generates pressure, the pressure contact plate 5 moves downward, causing the pressure sensing assembly to receive a signal. At this time, the lifting drive assembly 9 on the side that sends the signal is supported in place. If the pressure contact plate 5 on the other side does not send a signal, it means that there is a height difference in the cap beam. The lifting drive assembly 9 needs to continue to move upward to prop it up to the same height as the other side. When the pressure contact plates 5 on both sides send a signal, it means that the support is in place and the lifting drive assembly 9 stops rising to prevent excessive support from damaging the cap beam.

[0034] Refer to the attached Figure 2 Connecting blocks are provided at both ends of the driving connecting shaft 15, the driving connecting shaft 15 is rotatably connected to the connecting blocks, and the bottom of the connecting blocks is fixedly connected to the supporting plate.

[0035] According to the above structure, the connection block is used to fix the driving connection shaft 15 .

[0036] Refer to the attached Figure 2, the bottom of the driving motor 12 is fixedly connected to the supporting plate.

[0037] According to the above structure, the fixed connection between the driving motor 12 and the supporting plate can ensure the stability of the lifting driving assembly 9.

[0038] Refer to the attached Figure 1 - Figure 2 The two sides of the lifting support platform 3 are fixedly connected with sliding support blocks 8, and the lifting support column 2 is provided with a slide groove corresponding to the position of the sliding support block 8, and the sliding support block 8 is vertically slidably connected with the slide groove.

[0039] According to the above structure, the lifting support platform 3 slides up and down on one side of the lifting support column 2, and the sliding support block 8 can limit the position and support the cap beam at the same time, which can play the function of bearing stress.

[0040] Refer to the attached Figure 4 - Figure 5 The lifting drive assembly 9 is composed of two layers, an upper layer and a lower layer, and a buffer support spring 6 is fixedly connected between the bottom of the pressure contact plate 5 and the lifting drive assembly 9 of the lower layer.

[0041] According to the above structure, the upper and lower layers of the lifting drive assembly 9 can be more stable when supported, and the buffer support spring 6 is used to support the pressure contact plate 5. When the pressure contact plate 5 contacts the cap beam, it can play a buffering role. At the same time, when the pressure contact plate 5 is away from the cap beam, the buffer support spring 6 can make the pressure contact plate 5 return to its original position.

[0042] Refer to the attached Figure 5 The pressure sensing assembly includes a pressure transmission column 7, which is located below the pressure contact plate 5. The pressure transmission column 7 is fixedly connected to the pressure contact plate 5, and a pressure receiving column 20 is fixedly connected to the position of the lower lifting drive assembly 9 corresponding to the pressure transmission column 7.

[0043] According to the above structure, when the pressure contact plate 5 contacts the cap beam, the pressure contact plate 5 will move downward under the action of pressure. At this time, the pressure transmission column 7 under the pressure contact plate 5 contacts the pressure receiving column 20. The pressure transmission column 7 and the pressure receiving column 20 are connected to a power source. When the pressure transmission column 7 contacts the pressure receiving column 20, a passage is formed, and a pressure signal can be sent at this time.

[0044] Refer to the attached Figure 6 The pressure transmission column 7 includes a transmission column body 17, an active cavity is opened inside the transmission column body 17, a pressure transmission cap 18 is slidably connected in the active cavity, and a pressure buffer spring 19 is fixedly connected between the pressure transmission cap 18 and the inner wall of the sliding cavity.

[0045] According to the above structure, the design of the pressure transmission cap 18 is to prevent unevenness on the cap beam, which causes the pressure contact plate 5 to descend unevenly and leads to inaccurate signal transmission of the pressure transmission column 7.

[0046] The working principle of the utility model is as follows: when the driving motor 12 is started, the driving worm 11 is driven to rotate, and the driving worm 11 drives the driving turbine 13 to rotate, and the driving turbine 13 is fixedly connected to the driving connecting shaft 15 and will also rotate, and the driving gear plate 14 on the driving connecting shaft 15 can drive the lifting chain 10 to transmit, so that the position of the counterweight balance block 16 and the lifting support platform 3 is changed, so that the lifting support platform 3 can move to support the cap beam;

[0047] When the lifting support platform 3 supports the cap beam, the pressure contact plate 5 on the lifting drive assembly 9 first contacts the cap beam. When the cap beam and the pressure contact plate 5 contact and generate pressure, the pressure contact plate 5 will move downward, causing the pressure sensing assembly to send a signal. At this time, the lifting drive assembly 9 on the side that sends the signal is supported in place. If the pressure contact plate 5 on the other side does not send a signal, it means that there is a height difference in the cap beam. The lifting drive assembly 9 needs to continue to move upward to prop it up to the same height as the other side. When the pressure contact plates 5 on both sides send a signal, it means that the support is in place and the lifting drive assembly 9 stops rising to prevent excessive support from damaging the cap beam.

[0048] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
