Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a self-lifting device for a hanging basket sling. Background Art

[0002] During the construction of bridges, the elevation of the bridge needs to be adjusted frequently to meet the design requirements, and currently, slings are commonly used for adjustment. Chinese patent CN202222203156.2 discloses a safe and portable adjuster for steel slings, including a steel sling and an upper slider. The upper end surface of the upper slider is provided with a first through hole matching the steel sling, and the steel sling is evenly provided with sling holes along the axial direction. The steel sling is detachably connected to a pin through the sling hole. The upper end surface of the upper slider is fixedly connected to a holder, and a groove for placing the pin is provided on the holder. The lower slider is slidably connected to the lower slider on both sides of the bottom of the upper slider, and a second through hole matching the steel sling is provided inside the lower slider. A third through hole is provided inside the lower slider, and the lower slider is threadedly connected to a bidirectional threaded rod through the third through hole, and a nut is fixedly connected to one end of the bidirectional threaded rod. This adjuster solves the problem that the existing beam elevation device is inconvenient to accurately elevate.

[0003] The existing adjustment device has the following problems: during the sling adjustment process, construction workers are required to climb up the hanging basket several times and manually install or remove the pin shaft, and the adjustment process is cumbersome and has safety hazards.

[0004] Based on the above situation, there is an urgent need for a self-lifting device for a hanging basket sling to solve the problem of potential safety hazards in the adjustment process. Utility Model Content

[0005] The purpose of the utility model is to solve the problem of safety hazards in the existing adjustment device, in which, during the sling adjustment process, construction workers are required to climb up the hanging basket many times and manually install or remove the pin shaft. The adjustment process is cumbersome and there are safety hazards.

[0006] The technical solution of the utility model is as follows:

[0007] A self-lifting device for a hanging basket sling, comprising:

[0008] Support beams, used to bear weight;

[0009] a lifting mechanism, mounted on the support beam and used to adjust the height of the sling;

[0010] A limiting mechanism, used for limiting the position of the sling;

[0011] A distance meter is installed on the sling and is used to calibrate the limit mechanism.

[0012] In the existing adjustment device, during the sling adjustment process, construction workers are required to climb onto the hanging basket and manually install or remove the pin shaft. The adjustment process is cumbersome and there are safety hazards. In this solution, the elevation of the sling is adjusted by the lifting mechanism, and the rangefinder calibrates the limit mechanism and then limits the sling through the limit mechanism to keep the sling fixed, thereby avoiding the construction workers from manually installing or removing the pin shaft and solving the problem of safety hazards in the adjustment process.

[0013] Furthermore, the present solution does not limit the specific structure of the limiting mechanism. One feasible solution is: the limiting mechanism includes a jack and a limiting piece connected to the jack, and a plurality of limiting holes cooperating with the limiting piece are formed on the sling. When this solution is adopted, the jack drives the limiting piece to move, and the lifting height of the jack is calibrated by the rangefinder. When the limiting piece moves to the specified limiting hole, the limiting piece cooperates with the limiting hole to keep the sling fixed.

[0014] Furthermore, the present solution does not limit the specific structure of the limit member. One feasible solution is: the limit member includes a limit pin and a telescopic rod for driving the limit pin. When this solution is adopted, the telescopic rod is driven by the jack to synchronously rise and fall to the specified position, and the telescopic rod drives the limit pin to extend and insert into the specified limit hole, thereby realizing the automated installation and disassembly of the limit pin and solving the problem of complicated adjustment process.

[0015] Furthermore, in order to further fix the sling, one feasible solution is: a fixing block for assisting in fixing the limit pin is installed on the jack. When this solution is adopted, the fixing block cooperates with the jack to fix the limit pin, thereby improving the firmness of the sling.

[0016] Furthermore, the present solution does not limit the specific structure of the lifting mechanism. One feasible solution is: the lifting mechanism includes a gear and a motor for driving the gear, and a rack that cooperates with the gear is formed on the sling. When this solution is adopted, the gear is driven to rotate by the motor, thereby driving the sling to rise and fall.

[0017] Furthermore, an elevation receiving control system is installed on the support beam. When this solution is adopted, the elevation receiving control system scans the bridge pier and controls the lifting mechanism, thereby ensuring the accuracy of the sling elevation.

[0018] Compared with the existing technology, the beneficial effects of the utility model are:

[0019] 1. The elevation of the sling is adjusted by the lifting mechanism. The distance meter calibrates the limit mechanism and then limits the sling through the limit mechanism to keep the sling fixed, avoiding the manual installation or removal of the pin by construction personnel, and solving the problem of potential safety hazards in the adjustment process;

[0020] Second, since the limiting mechanism includes a jack and a limiting member connected to the jack, a plurality of limiting holes cooperating with the limiting member are formed on the sling, the jack drives the limiting member to move, and the lifting height of the jack is calibrated by the rangefinder, and when the limiting member moves to the specified limiting hole, the limiting member cooperates with the limiting hole to keep the sling fixed;

[0021] 3. Since the limit member includes a limit pin and a telescopic rod for driving the limit pin, the telescopic rod is driven by the jack to synchronously rise and fall to the specified position, and the telescopic rod drives the limit pin to extend and insert into the specified limit hole, thereby realizing the automatic installation and disassembly of the limit pin and solving the problem of complicated adjustment process.

[0033] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] Example:

[0036] Please refer to Figure 1 , a self-lifting device for a hanging basket sling, comprising:

[0037] Support beam 1, used for bearing weight;

[0038] A lifting mechanism 2, mounted on the support beam 1 and used to adjust the height of the sling 3;

[0039] A limiting mechanism 4, used for limiting the position of the sling 3;

[0040] The distance meter 5 is installed on the sling 3 and is used to calibrate the limiting mechanism 4.

[0041] In the existing adjustment device, during the sling adjustment process, construction workers are required to climb onto the hanging basket and manually install or remove the pin shaft. The adjustment process is cumbersome and there are safety hazards. In this solution, the elevation of the sling 3 is adjusted by the lifting mechanism 2, and the rangefinder 5 calibrates the limit mechanism 4 and then limits the sling 3 by the limit mechanism 4 to keep the sling 3 fixed, thereby avoiding the construction workers from manually installing or removing the pin shaft and solving the problem of safety hazards in the adjustment process.

[0042] This solution does not limit the specific structure of the limiting mechanism 4. One feasible solution is: the limiting mechanism 4 includes a jack 41 and a limiting member 42 connected to the jack 41, and a plurality of limiting holes 31 cooperating with the limiting member 42 are formed on the sling 3. Specifically, in this embodiment, a jack 41 is installed on each side of the sling 3, and two rangefinders 5 are installed on the sling 3, and the two rangefinders 5 are respectively used to calibrate the corresponding jacks 41. When this solution is adopted, the jack 41 drives the limiting member 42 to move, and the lifting height of the jack 41 is calibrated by the rangefinder 5. When the limiting member 42 moves to the specified limiting hole 31, the limiting member 42 cooperates with the limiting hole 31 to keep the sling 3 fixed.

[0043] The present solution does not limit the specific structure of the limit member 42. One feasible solution is: the limit member 42 includes a limit pin 421 and a telescopic rod 422 for driving the limit pin 421. When this solution is adopted, the telescopic rod 422 is driven by the jack 41 to synchronously rise and fall to the specified position, and the telescopic rod 422 drives the limit pin 421 to extend and insert into the specified limit hole 31, thereby realizing the automated installation and disassembly of the limit pin 421 and solving the problem of complicated adjustment process.

[0044] In order to further fix the sling 3, one feasible solution is: a fixing block 43 for assisting in fixing the limit pin 421 is installed on the jack 41. When this solution is adopted, the fixing block 43 cooperates with the jack 41 to fix the limit pin 421, thereby improving the firmness of the sling 3.

[0045] This solution does not limit the specific structure of the lifting mechanism 2. One feasible solution is: the lifting mechanism 2 includes a gear 21 and a motor 22 for driving the gear 21. A rack 32 that cooperates with the gear 21 is formed on the sling 3. When this solution is adopted, the motor 22 drives the gear 21 to rotate, thereby driving the sling 3 to rise and fall.

[0046] Optionally, in this embodiment, the motor 22 is a stepping motor. When this solution is adopted, the height adjustment of the sling 3 can be made more precise by controlling the number and frequency of current pulses.

[0047] An elevation receiving control system 6 is installed on the support beam 1. When this solution is adopted, the elevation receiving control system 6 scans the bridge pier and controls the lifting mechanism 2, so that the accuracy of the elevation of the sling 3 can be guaranteed.

[0048] The working principle of this embodiment:

[0049] The elevation of the support beam 1 is obtained by scanning the bridge pier through the elevation receiving control system 6, and the gear 21 is driven by the motor 22 to rotate to adjust the elevation of the sling 3. The two rangefinders 5 respectively measure the distance to the corresponding fixed blocks 43, and the corresponding jacks 41 are raised and lowered to the specified position through feedback control. The telescopic rod 422 extends the limit pin 421 and inserts it into the specified limit hole 31, and the sling 3 is supported and fixed by the two jacks 41.

[0050] In order to solve the problem of potential safety hazards in the adjustment process, in this solution, the elevation of the sling 3 is adjusted by the lifting mechanism 2, the rangefinder 5 calibrates the limit mechanism 4 and then limits the sling 3 by the limit mechanism 4 to keep the sling 3 fixed, avoiding the construction personnel from manually installing or removing the pin shaft, and solving the problem of potential safety hazards in the adjustment process.

[0051] In order to fix the sling 3, in this solution, since the limiting mechanism 4 includes a jack 41 and a limiting member 42 connected to the jack 41, a plurality of limiting holes 31 cooperating with the limiting member 42 are formed on the sling 3. The jack 41 drives the limiting member 42 to move, and the lifting height of the jack 41 is calibrated by the rangefinder 5. When the limiting member 42 moves to the specified limiting hole 31, the limiting member 42 cooperates with the limiting hole 31 to keep the sling 3 fixed.

[0052] In order to solve the problem of the complicated adjustment process, in the present solution, since the limit member 42 includes a limit pin 421 and a telescopic rod 422 for driving the limit pin 421, the telescopic rod 422 is driven by the jack 41 to synchronously rise and fall to the specified position, and the telescopic rod 422 drives the limit pin 421 to extend and insert into the specified limit hole 31, thereby realizing the automated installation and disassembly of the limit pin 421 and solving the problem of the complicated adjustment process.
