Description

Technical Field

[0001] The present invention belongs to the technical field of culvert construction, and particularly relates to a culvert auxiliary lifting device and a culvert lifting construction process. Background Art

[0002] With the continuous development of society, concrete culverts for rainwater and sewage pipelines in municipal engineering are increasingly widely used. In the construction of reinforced concrete culverts, culverts are usually prefabricated centrally in factories and assembled on site. The traditional culvert installation process uses a lifting device and a steel wire rope for lifting operations. During the lifting process, the steel wire rope often causes damage to the outer wall of the pipeline. At the same time, there are certain safety risks in the fixation of the steel wire rope. Currently, a culvert auxiliary lifting device is usually used to lift the culvert to avoid the direct connection between the steel wire rope and the pipeline to cause damage to the outer wall of the pipeline. However, the culvert auxiliary lifting device usually cannot achieve precise docking of adjacent culverts during the lifting process, resulting in low installation efficiency and long adjustment time.

Detailed implementation mode

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments. Based on this embodiment, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Refer to Figures 1 to 4 , this embodiment proposes a pipe culvert auxiliary hoisting device, which includes a first hook arm 1, a second hook arm 2 and a connecting arm 3. The first hook arm 1 and the second hook arm 2 are arranged in parallel at intervals. The connecting arm 3 is used to connect the first hook arm 1 and the second hook arm 2. The first hook arm 1, the second hook arm 2 and the connecting arm 3 enclose a containing space. A sling assembly 4 is provided on the first hook arm 1. The sling assembly 4 can be connected to an external hoisting device to realize the hoisting of the pipe culvert 7. A telescopic ruler 5 is provided at the bottom of the first hook arm 1. The connecting arm 3 is rotatably installed on the first hook arm 1 and is fixedly connected to the second hook arm 2 at the lower end. A lifting column assembly 6 is provided on the second hook arm 2. The lifting column assembly 6 is used to adjust the height of the supporting pipe culvert 7. In this way, by setting the sling assembly 4, the hoisting of the pipe culvert 7 can be realized by connecting the hoisting device with the sling assembly 4. By setting the telescopic ruler 5, when the pipe culverts 7 are docked, the alignment can be carried out through the telescopic ruler 5 to ensure that the alignment of adjacent pipe culverts 7 and the installed pipe culverts is straight. By setting the lifting column assembly 6, the supporting height of the pipe culvert 7 can be adjusted according to actual needs, further improving the accuracy and efficiency of the docking of the pipe culvert 7. In addition, by rotatably installing the connecting arm 3 on the second hook arm 2, different types of hoisting devices can be satisfied, improving the practicability of the auxiliary hoisting device.

[0018] Specifically, please refer to Figure 1 As shown, a containing groove is provided at the bottom of the first hook arm 1, and a telescopic ruler 5 is provided in the containing groove. The bottom surface of the telescopic ruler 5 is flush with the bottom surface of the first hook arm 1. By setting the containing groove, when the telescopic ruler 5 is not in use, the telescopic ruler 5 can be stored in the containing groove, thereby preventing the telescopic ruler 5 from protruding from the outer wall of the first hook arm 1, and further preventing the telescopic ruler 5 from colliding with surrounding objects and being damaged during transportation or movement, improving the service life of the telescopic ruler 5.

[0019] Specifically, please refer to Figure 1 and Figure 2As shown, a support and a bearing 14 are provided inside the first hook arm 1. The connecting arm 3 is rotatably installed on the first hook arm 1 through the support and the bearing 14. Clamping devices 13 are provided on the outer sides of both sides of the connecting arm 3. The clamping devices 13 are symmetrically and fixedly installed at the bottom of the first hook arm 1. Manually assist in rotating the second hook arm 2, so that the rotation positioning of the connecting arm 3 can be realized through the clamping devices 13, adapting to the lifting requirements of different construction machinery and equipment such as excavators, loaders or cranes at the construction site. The clamping device 13 is mainly composed of an electric push rod and a clamping clip. When it is necessary to position the connecting arm 3 after rotation, the clamping clip is pushed by the electric push rod to hold the connecting arm 3, thereby realizing positioning. Of course, it can also be designed into other forms of clamping devices.

[0020] Specifically, please refer to Figure 1. The lifting column assembly 6 includes a hydraulic lifting column 61, an arc plate 62 and a controller 63. The hydraulic lifting columns 61 are arranged at intervals on the second hook arm 2. The arc plate 62 is arranged on the hydraulic lifting column 61 and abuts against the culvert 7. The controller 63 is arranged on one side of the second hook arm 2 and is used to control the lifting of the hydraulic lifting column 61. A channel 64 is opened on the second hook arm 2 for the hydraulic lifting column 61 to be electrically connected to the controller 63. By providing the hydraulic lifting column 61, the precise adjustment of the support height of the culvert 7 can be realized. At the same time, by providing the arc plate 62, the contact area between the hydraulic lifting column 61 and the culvert 7 can be increased, improving the stability of the culvert 7. The setting of the controller 63 can facilitate the operator to control the lifting of the hydraulic lifting column 61, improving the construction efficiency. In addition, by opening the channel 64 on the second hook arm 2, the electrical connection between the hydraulic lifting column 61 and the controller 63 can be realized, so that the lifting of the hydraulic lifting column 61 can be precisely controlled through the controller 63.

[0021] Specifically, the controller 63 controls the height of each hydraulic lifting column 61 respectively. In this way, according to the actual situation of the culvert 7, the hydraulic lifting columns 61 at different positions can be controlled separately through the controller 63 to realize the independent adjustment of the support height of the culvert 7, ensuring the stability and safety of the culvert 7 during the lifting process. For example, when one end of the culvert 7 needs to be slightly lifted to match the height of the butt-jointed culvert 7, the operator can separately adjust the hydraulic lifting column 61 at this end through the controller 63 without adjusting the height of the entire culvert 7, thereby improving the flexibility and efficiency of the construction.

[0022] In addition, the auxiliary pipe culvert lifting device further includes an infrared sensor 65 for monitoring the level of the pipe culvert 7. The infrared sensors 65 are respectively arranged on each hydraulic lifting column 61 and are at the same horizontal position. The corresponding positions of the arc-shaped plate 62 are provided with openings for the installation and measurement of the infrared sensors 65. During the lifting process, the infrared sensor 65 can monitor the horizontal state of the pipe culvert 7 in real time. Once it is found that the pipe culvert 7 is tilted or unbalanced, the operator can immediately adjust the corresponding hydraulic lifting column 61 through the controller 63 to ensure that the pipe culvert 7 always maintains a horizontal position.

[0023] Specifically, each infrared sensor 65 in this embodiment is equipped with a transmitter and a receiver, which respectively emit infrared rays to different parts of the pipe culvert 7 and receive the reflected signals. By calculating the time difference or phase difference between the transmitted and received signals, the distance of each part of the pipe culvert 7 relative to the infrared sensor 65 can be accurately measured, thereby judging its horizontal state. When the pipe culvert 7 is tilted or unbalanced during the lifting process, the distance between some parts and the infrared sensor 65 will change. This change will be quickly captured by the infrared sensor 65 and converted into an electrical signal, and then transmitted to the controller 63. After receiving the signal, the controller 63 will immediately analyze and determine the hydraulic lifting column 61 that needs to be adjusted and its adjustment amount, and then issue an instruction to perform the corresponding adjustment operation. This process realizes the real-time monitoring and precise adjustment of the horizontal state of the pipe culvert 7, ensuring the safety and stability of the lifting process.

[0024] Specifically, please refer to Figure 1 As shown, the sling assembly 4 includes a first sling 41 and a second sling 42. The first sling 41 is fixedly installed on the first hook arm 1, and the second sling 42 is slidably installed on the first hook arm 1. Specifically, the cross-section of the first hook arm 1 is square, and the second sling 42 is provided with a sliding groove, which can be connected with the first hook arm 1 in a matching manner.

[0025] Specifically, please refer to Figure 1 As shown, the auxiliary pipe culvert lifting device further includes a fixing member (not shown in the drawings), and the fixing member can be used to fix the second sling 42 to the first hook arm 1. Specifically, the first hook arm 1 is provided with fixing holes 11 at intervals along its length direction, and the second sling 42 is provided with through holes 421. The fixing member passes through the through holes 421 in sequence and is connected with the fixing holes 11. In this way, when the position of the second sling 42 needs to be adjusted, after sliding the second sling 42 to a preset position, the fixing member passes through the through hole 421 and is connected with the fixing holes 11 at different positions, so as to realize the adjustment of the position of the second sling 42, which is simple and convenient. Specifically, the fixing member is a bolt, and the fixing hole 11 is a threaded hole. Of course, in this application, the fixing member can also be a pin shaft, and the fixing hole 11 can also be provided as a light hole, etc., which is not limited uniquely here.

[0026] Specifically, please refer to Figure 1 As shown, a counterweight 12 is provided at the left end of the first hook arm 1, and the first lifting ring 41 is arranged on the counterweight 12. When the auxiliary lifting device is connected to a heavier or longer culvert, the stress point of the first hook arm 1 mainly concentrates on the end connected to the connecting arm 3. If the counterweight 12 is not provided, the other end of the first hook arm 1 may lack the corresponding weight, resulting in uneven overall stress, which may cause deformation or overturning of the hook arm, thereby affecting the stability and safety of the lifting. The setting of the counterweight 12 makes the whole hook arm more balanced when stressed by increasing the weight of the other end of the first hook arm 1, effectively avoiding the deformation problem caused by uneven stress, thus improving the efficiency and safety of the lifting operation.

[0027] Specifically, please refer to Figure 1 As shown, the culvert auxiliary lifting device further includes a third lifting ring 43, and the third lifting ring 43 is arranged on the side of the first hook arm 1 opposite to the telescopic ruler 5. In this way, the longitudinal and lateral positions of the culvert can be manually adjusted through the third lifting ring 43 to achieve the precise docking effect.

[0028] Specifically, please refer to Figure 3 and Figure 4 As shown, the first lifting ring 41 of the culvert auxiliary lifting device is connected to the hook of the lifting equipment 8 through a manual hoist 81 and a rope 82, and the second lifting ring 42 is connected to the hook of the lifting equipment 8 through a rope 82. By adjusting the manual hoist 81 to take in and release, the height of one end of the second hook arm 2 can be adjusted, so that the horizontal angles at both ends of the second hook arm 2 can be adjusted, ensuring the balance before the culvert is lifted and providing guarantee for the stable lifting of the culvert.

[0029] Please refer to Figure 5 As shown, this embodiment also provides a culvert lifting construction process, including the following steps: S01: Excavating the trench; S02: Connecting the culvert auxiliary lifting device to the hanging point on the lifting equipment; S03: Using the culvert auxiliary lifting device to lift the culvert, adjusting the horizontal angle of the culvert so that the culvert is in a horizontal position, then transporting it to the preset position, unfolding the telescopic ruler, and manually assisting to adjust the telescopic ruler to fit the outer side wall of the 3 - 5 sections of the culvert that have been installed to adjust the overall line type. At the same time, adjusting the vertical height of the culvert to make it level with the height of the docking culvert and completing the docking; S04: Removing the culvert auxiliary lifting device and completing the backfilling of the culvert.

[0030] Specifically, through trench excavation, the backfill position of the culvert is prepared in advance; subsequently, the culvert auxiliary lifting device is connected to the hanging point on the lifting equipment, enabling the culvert to be lifted. During the lifting process, the horizontal angle of the culvert can be adjusted through the culvert auxiliary lifting device to make the culvert in a horizontal position; when it is moved to the preset position, by unfolding the telescopic ruler, one end of the telescopic ruler is closely attached to the outer wall of the culvert section to be docked to ensure the straightness of the overall culvert line. At this time, the operator can adjust the height of the lifting column assembly again to make the lifted culvert completely aligned with the docked culvert in height. This fine-tuning mechanism ensures the accuracy of culvert docking and reduces the docking error caused by height mismatch; after docking, the operator can remove the culvert auxiliary lifting device and fill the trench around the culvert with backfill material. During the backfill process, it should be ensured that the backfill material is evenly compacted to avoid culvert displacement or deformation caused by improper backfill.

[0031] Please refer to Figure 6 as shown, the step S03 includes: S031: Insert the culvert auxiliary lifting device into the socket of the culvert and lift the culvert using the lifting equipment; S032: Adjust the lifting column assembly to adjust the horizontal angle of the culvert to make it in a horizontal position, and then transport it to the preset position; S033: Unfold the telescopic ruler, and manually assist in adjusting to make the telescopic ruler fit the outer wall of the culvert to be docked to adjust the overall culvert line, and adjust the height of the lifting column assembly to make the lifted culvert level with the docked culvert in height.

[0032] Specifically, during the lifting process, the time difference or phase difference between the signal transmission and reception of the infrared sensor 65 can be used to accurately measure the distance of each part of the culvert 7 relative to the sensor, thereby determining its horizontal state. When the culvert 7 is tilted or unbalanced, the distance between certain parts and the infrared sensor 65 will change. This change will be quickly captured by the infrared sensor 65 and converted into an electrical signal, which is then transmitted to the controller 63. After receiving the signal, the controller 63 will immediately analyze and determine the hydraulic lifting column 61 that needs to be adjusted and its adjustment amount, and then issue an instruction for the corresponding adjustment operation. This process realizes the real-time monitoring and precise adjustment of the horizontal state of the culvert 7, ensuring the safety and stability of the lifting process. By expanding the retractable ruler 5 and manually assisting in the adjustment through the third lifting ring to make the retractable ruler fit the outer wall of the culvert to be docked, the culvert line type is adjusted, and the height of the lifting column assembly 6 is adjusted so that the culvert lifted is completely aligned with the culvert to be docked in height. This design not only improves the accuracy of culvert docking but also reduces the possible errors during the docking process, ensures the overall line type, and guarantees the construction quality of the project. During the adjustment process, the operator can observe the level and height of the culvert 7 and use the controller to finely adjust the hydraulic lifting column 61 to achieve the best docking effect. After the docking is completed, the operator can further fill the trench around the culvert with backfill material to ensure the stability and safety of the culvert.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of the present invention.
