Description

Technical Field

[0001] The utility model relates to the technical field of lifting structures, in particular to a pipe assembly unit hoisting structure for assembled electromechanical construction. Background Art

[0002] In recent years, the research and application of domestic prefabricated electromechanical installation technology have been launched one after another. Prefabricated electromechanical installation is based on modular design and industrial prefabrication of electromechanical pipelines. Combined with pipeline materials, connection methods, etc., the electromechanical pipelines are divided into a combination with an integrated bracket as the connecting link, namely the pipe group assembly unit.

[0003] At present, the installation of integrated pipelines in mechanical and electrical installation projects mainly relies on manpower, or manpower and manual hoists to install the integrated pipelines one by one on the pre-installed integrated bracket base. This method has high labor intensity, low labor efficiency, long construction period, high safety risks, and difficult quality control. It is no longer in line with the requirements for high-quality development of my country's construction industry.

[0004] The existing electromechanical pipeline hoisting process is: (comprehensive) bracket base installation → manual hoist lifting point and hoist installation → pipeline hoisting and assembly. It has the following defects:

[0005] 1. The lifting process of electromechanical pipelines is completed by manual hoists and manual cooperation. Generally, the bracket base is installed first, and the lifting point of the manual hoist is set near the bracket base. Then, the pipe assembly unit is lifted into place by the manual hoist, and the bracket upright is installed on the bracket base. This method has poor lifting accuracy and the bracket base is positioned and installed first, which makes it difficult to accurately position the bracket. The quality of bracket installation cannot be guaranteed. In addition, the installation of pipe brackets, pipeline lifting and assembly are mainly carried out at high altitudes, with complex construction steps, many high-altitude operations, and difficult quality control;

[0006] 2. Comprehensive support, pipe hoisting and assembly require a large amount of labor, with low labor efficiency and a long construction period;

[0007] 3. Pipeline hoisting mainly relies on manpower or manual hoists, and personnel operate under the hoisting components, which is unsafe. The manual hoist has poor operation accuracy and synchronization, and has high labor intensity. The pipe assembly unit is limited by the manual hoist's own travel, and there is a "blind spot" in the lifting height.

[0008] 4. It is impossible to achieve accurate positioning during the rising process of the pipe assembly unit;

[0009] 5. The current lifting device cannot achieve two-way lifting and can only install a single bracket, which has certain functional defects in actual use. Utility Model Content

[0010] Based on the technical problems pointed out in the background technology regarding the use of a manual hoist to lift a pipe group assembly unit, the purpose of the present application is to propose a pipe group assembly unit lifting structure, which adopts a bidirectional jack and can achieve lifting in two directions at the same time. At the same time, auxiliary lifting components can be installed on the upper and lower ends of the bidirectional jack, which can support the bidirectional jack during the lifting process, thereby improving the safety of the lifting structure and meeting the functionality of the lifting structure.

[0011] The utility model is realized by the following technical solutions:

[0012] The present application provides a pipe group assembly unit lifting structure, including a hollow bidirectional jack, wherein the upper and lower ends of the bidirectional jack are connected to auxiliary lifting components; a lifting screw is passed through the middle of the bidirectional jack and the auxiliary lifting component, and a safety auxiliary support nut for supporting the auxiliary lifting component is connected to the lifting screw; and a lifting hook is connected to the top of the lifting screw.

[0013] Among them, the hollow two-way jack can be lifted up and down by filling and draining oil, and the computer analyzes and automatically controls the hydraulic cylinder to lift up and down synchronously.

[0014] It should be noted that the lifting screw is passed through the middle of the hollow two-way jack and auxiliary lifting assembly, and is not directly connected to the hollow two-way jack and auxiliary lifting assembly. There is a certain amount of movable gap between the lifting screw and the hollow two-way jack and auxiliary lifting assembly.

[0015] The hoisting structure adopts a hollow bidirectional jack, which can realize jacking in two directions at the same time. At the same time, auxiliary lifting components can be installed on the upper and lower ends of the bidirectional jack, which can realize the supporting effect of the bidirectional jack during the jacking process, improve the safety of the hoisting structure, and meet the functionality of the hoisting structure. In addition, the hoisting structure makes the positioning accuracy of the pipe group assembly unit high and the synchronization good. Personnel can operate in a safe place, reduce high-altitude operations, mainly rely on mechanical operations, effectively reduce labor intensity and safety risks, save labor costs, and improve construction quality.

[0016] In addition, a lifting screw is inserted between the auxiliary lifting component and the hollow bidirectional jack, which not only enables lifting, but also adopts a screw structure, so that the locking support of the auxiliary lifting component can be achieved only by connecting and installing an auxiliary support nut on the screw. Moreover, the lifting screw installed in the middle also has a certain guiding effect, so that the lifting structure will not deviate as a whole during use.

[0017] Furthermore, the auxiliary lifting assembly includes an auxiliary support frame, both ends of which are respectively connected with connecting flanges for fixing the support pole fixing angle code and the hollow two-way jack, and the upper and lower ends of the support pole fixing angle code are provided with connecting fixing plates, and the connecting fixing plates are fixed to the connecting flange by bolts; the lifting screw passes through the middle of the connecting flange; the support pole fixing angle code fixes the support pole of the pipe group assembly unit by T-bolts and J-bolts.

[0018] The size of the auxiliary support frame at the upper end of the two-way jack and the auxiliary support frame at the lower end of the two-way jack can be the same or different. The appropriate support frame body is selected according to the size of the connected bracket. The larger the size, the more stable it is. The height of the auxiliary support frame at the upper end can be greater than the height of the auxiliary support frame at the lower end, or the height of the auxiliary support frame at the upper end can be less than the height of the auxiliary support frame at the lower end, or the height of the auxiliary support frame at the upper end can be equal to the height of the auxiliary support frame at the lower end.

[0019] Among them, the support upright is connected to the support cross arm.

[0020] The connecting fixing plate of the auxiliary lifting assembly and the fixing angle bracket of the support pole is fixed by flange connection, so that the disassembly and installation of the lifting structure are very convenient.

[0021] During actual installation, align the connecting fixing plate at the upper end of the bracket upright fixing angle code with the connecting flange at the upper end of the auxiliary support frame; align the connecting fixing plate at the lower end of the bracket upright fixing angle code with the connecting flange at the lower end of the auxiliary support frame, and at the same time align the connecting flange at the upper end of the two-way jack with the connecting fixing plate at the lower end of the bracket upright fixing angle code, that is, the connecting fixing plate at the lower end of the bracket fixing angle code is located between the connecting flanges of the auxiliary support frame and the two-way jack, and the three can be locked and fixed by the locking bolts.

[0022] Furthermore, the bolt holes provided on the fixing angle brackets of the support uprights are strip-shaped bolt holes.

[0023] The strip bolt holes arranged on the bracket pole fixing angle brackets can realize the fixing of bracket poles of different specifications and sizes.

[0024] Furthermore, a safety auxiliary support nut is connected to the lifting screw at the bottom of the connecting flange at the upper end of the auxiliary support frame, and a stabilizing structure is installed at the lower end of the safety auxiliary support nut.

[0025] Furthermore, a plurality of fixing bolts are installed around the safety auxiliary support nut.

[0026] Furthermore, the stabilizing structure includes a slip ring body slidably mounted on the auxiliary support frame, the slip ring body is provided with a guide slider, the auxiliary support frame is provided with a guide slot for mounting the guide slider, and the guide slider is fixed by a slider bolt.

[0027] Furthermore, the lifting screw rod is composed of an upper rod and a lower rod, and the upper rod is threadedly connected to the lower rod.

[0028] The upper rod and the lower rod can both be hollow structures, and an internal thread can be provided inside the upper rod and an external thread can be provided outside the lower rod; or an internal thread can be provided inside the lower rod and an external thread can be provided outside the upper rod. When installing, the upper rod and the lower rod can be directly tightened.

[0029] The lifting auxiliary rod adopts a structure in which the upper rod and the lower rod are threadedly connected. The length of the lifting auxiliary rod can be adjusted according to the actual lifting height. It is suitable for lifting at different stroke heights and can be repeatedly used in all positions.

[0030] Furthermore, a U-shaped connecting block is connected to the top of the lifting screw rod, and the lifting hook is fixed to the U-shaped connecting block by bolts.

[0031] Furthermore, the hook is a universal hook.

[0032] The universal hook can rotate 360°, which is convenient for adjusting the lifting screw. A lifting eye nut can be installed on the upper part of the lifting screw to connect the universal hook and the lifting screw.

[0033] Furthermore, a laser displacement sensor is connected to the hollow bidirectional jack.

[0034] The laser displacement sensor transmits the displacement data of each lifting cylinder back to the control center, and the computer analyzes and automatically controls the synchronous lifting of the hydraulic cylinders. A high-precision non-contact touch sensor is installed at the base of each bracket. When any bracket pole of the pipe assembly unit is lifted to the predetermined position, the touch sensor controls all lifting cylinders to stop to ensure the safety of the lifting process. The control center can also analyze and process the displacement data sent back, and fine-tune each lifting cylinder through the computer until the installation accuracy requirements of the pipe assembly unit are met.

[0059] Example 1

[0060] like Figures 1 to 11 As shown, this embodiment provides a pipe assembly unit hoisting structure, including a hollow two-way jack 01, the upper and lower ends of the hollow two-way jack 01 are connected to auxiliary lifting components; a hoisting screw 11 is passed through the middle of the hollow two-way jack 01 and the auxiliary lifting component, and a safety auxiliary support nut 20 for supporting the auxiliary lifting component is connected to the hoisting screw 11; the top of the hoisting screw 11 is connected to a hook. The two-way jack 01 can be lifted up and down by filling and draining oil, and the hydraulic cylinder is automatically controlled to lift up and down synchronously through computer analysis. The bracket crossbar 08 is connected to the bracket upright 06.

[0061] The auxiliary lifting assembly in this embodiment includes an auxiliary lifting assembly 12 connected above the bidirectional jack 01 and an auxiliary lifting assembly 2 13 connected below the bidirectional jack 01 .

[0062] Specifically, Figures 1 to 4As shown, the auxiliary lifting assembly includes an auxiliary support frame 16, and both ends of the auxiliary support frame 16 are respectively connected with connecting flanges 14 for fixing the support upright fixing angle code 04 and the hollow two-way jack 01; the upper and lower ends of the support upright fixing angle code 04 are provided with connecting fixing plates 02, and the connecting fixing plate 02 and the connecting flange 14 are fixed by bolts; the lifting screw 11 passes through the middle of the connecting flange 14 (the lifting screw 11 is not connected to the connecting flange, and a through hole is provided in the middle of the connecting flange 14, and the lifting screw 11 passes through the through hole); the support upright fixing angle code 04 is fixed to the support upright 06 of the pipe group assembly unit by T-bolts 07 and J-bolts 05. The size of the auxiliary support frame 16 at the upper end of the two-way jack 01 and the auxiliary support frame 16 at the lower end of the two-way jack 01 can be the same or different. A suitable support frame body is selected according to the size of the connected bracket. The larger the size, the more stable it is. The height of the auxiliary support frame 16 at the upper end can be greater than the height of the auxiliary support frame 16 at the lower end, or the height of the auxiliary support frame 16 at the upper end can be less than the height of the auxiliary support frame 16 at the lower end, or the height of the auxiliary support frame 16 at the upper end can be equal to the height of the auxiliary support frame 16 at the lower end.

[0063] like Figure 2 and Figure 4 As shown, the height of the upper auxiliary support frame 16 in this embodiment is greater than the height of the lower auxiliary support frame 16, and can be adjusted and installed according to actual needs during specific use.

[0064] During actual installation, align the connecting fixing plate 02 at the upper end of the bracket upright fixing angle code 04 with the connecting flange 14 at the upper end of the auxiliary support frame 16; align the connecting fixing plate 02 at the lower end of the bracket upright fixing angle code 04 with the connecting flange 14 at the lower end of the auxiliary support, and at the same time align the connecting flange 14 at the upper end of the two-way jack 01 with the connecting fixing plate 02 at the lower end of the bracket upright fixing angle code 04, that is, the connecting fixing plate 02 at the lower end of the bracket upright fixing angle code 04 is located between the connecting flange 14 of the auxiliary support frame 16 and the two-way jack 01, and the three can be locked and fixed by the locking bolts.

[0065] Specifically, in order to fix the support poles 06 of different specifications and sizes, the bolt holes provided on the support pole fixing angle code 04 are strip-shaped bolt holes.

[0066] Specifically, Figures 5 to 7 As shown, a stabilizing structure is installed at the lower end of the safety auxiliary support nut 20, and the stabilizing structure includes a slip ring body 15 slidably installed on the auxiliary support frame 16, a guide slider 18 is provided on the slip ring body 15, and a guide groove 21 for installing the guide slider 18 is provided on the auxiliary support frame 16, and the guide slider 18 is fixed by a slider bolt 19; four fixing bolts 17 are installed around the safety auxiliary support nut 20.

[0067] Specifically, Figure 3 As shown, the lifting screw 11 is composed of an upper rod 11-1 and a lower rod 11-2, and the upper rod 11-1 is threadedly connected to the lower rod 11-2. The upper rod 11-1 and the lower rod 11-2 can both be hollow structures, and an internal thread can be set inside the upper rod 11-1, and an external thread can be set outside the lower rod 11-2; or a structure in which an internal thread is set inside the lower rod 11-2 and an external thread is set outside the upper rod 11-1 can be adopted. During installation, the upper rod 11-1 and the lower rod 11-2 can be directly tightened. The lifting screw 11 adopts a structure in which the upper rod 11-1 and the lower rod 11-2 are threadedly connected. The length of the lifting screw 11 can be adjusted according to the actual lifting height, which is suitable for lifting at different stroke heights and can be repeatedly used in all positions.

[0068] Specifically, a U-shaped connection block is connected to the top of the lifting screw 11, and the universal hook 09 is fixed to the U-shaped connection block by bolts. The universal hook 09 of the connection structure can rotate 360 ​​degrees, which is convenient for adjusting the lifting screw 11. The upper part of the lifting screw 11 can be installed with a lifting eye nut 10 to connect the universal hook 09 and the lifting screw 11.

[0069] Specifically, in order to achieve accurate positioning of the support pole 06, a laser displacement sensor 03 is connected to the hollow bidirectional jack 01. In actual installation, a laser displacement sensor 03 is installed at each lifting point to transmit the displacement data of each lifting cylinder back to the control center, which is analyzed and automatically controlled by a computer to synchronously lift the hydraulic cylinder. A high-precision non-contact touch sensor is installed at the position of each support base. When any support pole 06 of the pipe assembly unit is lifted to a predetermined position, the touch sensor controls all lifting cylinders to stop to ensure the safety of the lifting process. Similarly, the control center can analyze and process the displacement data transmitted back, and fine-tune each lifting cylinder through a computer until the installation accuracy requirements of the pipe assembly unit are met.

[0070] Among them, the laser displacement sensor 03 is a sensor that uses laser technology for measurement. It is composed of a laser, a laser detector and a measurement circuit, and can accurately measure the position, displacement and other changes of the measured object without contact. It can measure precise geometric measurements such as location, thickness, vibration, distance, diameter, etc. In this embodiment, the laser displacement sensor 03 can use a conventional laser displacement sensor 03 in the prior art. Therefore, its structure and principle will not be elaborated too much in this application.

[0071] Among them, the touch sensor is a touch switch module based on capacitive sensing. When the human body or metal directly touches the metal surface on the sensor, it can be sensed. In addition to directly touching the metal surface, it can also be sensed through a certain thickness of plastic, glass and other materials. The sensing sensitivity is related to the size of the metal surface and the thickness of the covering material. In this embodiment, the touch sensor also uses a conventional touch sensor in the prior art, so its structure and principle will not be elaborated in this application.

[0072] There are mainly two operating methods for this lifting structure in actual use:

[0073] 1. The pipe assembly unit hoisting structure is lifted upward: the safety auxiliary support nut 20 of the slip ring body 15 controlled by the auxiliary lifting component 1 12 and the auxiliary lifting component 2 13 is initially in a locked state. The two-way jack 01 is supplied with oil, and the upper part of the two-way jack 01 is lifted upward, and the auxiliary lifting component 12 is lifted synchronously with the jack. The safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 is driven by the slip ring and rotates and rises synchronously with the jack. The safety auxiliary support nut 20 at the lower part of the auxiliary lifting component 13 plays a supporting role. After the lifting reaches a predetermined stroke, the oil supply is stopped, and the safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 is in a locked state; the two-way jack 01 is released from the oil, and the lower part of the two-way jack 01 is lifted upward, and the auxiliary lifting component 2 13 is lifted synchronously with the two-way jack 01. The safety auxiliary support nut 20 at the lower part of the auxiliary lifting component 2 13 is driven by the slip ring and rotates and rises synchronously with the jack. The safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 plays a supporting role. After the lifting reaches a predetermined stroke, the oil supply is stopped, and the safety auxiliary support nut 20 of the auxiliary lifting component 2 13 is in a locked state, and a lifting stroke is completed at this time.

[0074] 2. The pipe assembly unit hoisting structure is lifted downward: the safety auxiliary support nut 20 of the slip ring body 15 controlled by the auxiliary lifting component 1 12 and the auxiliary lifting component 2 13 is initially in a locked state. The two-way jack 01 is supplied with oil, and the lower part of the two-way jack 01 is lifted downward, and the auxiliary lifting component 13 is lifted synchronously with the jack. The safety auxiliary support nut 20 at the lower part of the auxiliary lifting component 13 is driven by the slip ring and rotates and descends synchronously with the jack. The safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 plays a supporting role. After the lifting reaches a predetermined stroke, the oil supply is stopped, and the installation auxiliary support nut at the lower part of the auxiliary lifting component 13 is in a locked state; the two-way jack 01 is drained, and the upper part of the two-way jack 01 is lifted downward, and the upper auxiliary lifting component is lifted synchronously with the jack. The safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 is driven by the slip ring and rotates and descends synchronously with the jack. The safety auxiliary support nut 20 at the lower part of the auxiliary lifting component 13 plays a supporting role. After the lifting reaches a predetermined stroke, the oil discharge is stopped, and the safety auxiliary support nut 20 at the upper part of the auxiliary lifting component 12 is in a locked state, and a lifting stroke is completed at this time.
