On the other hand, the invention also provides an adjusting method of the alternate lifting type hydraulic climbing frame, which comprises the following steps:
s1: the hydraulic climbing frame is configured, a plurality of wall-attached supporting seats (1) are arranged on a wall body in an array mode, and a guide rail (2) extending vertically is connected with the wall-attached supporting seats (1) in a sliding mode respectively; limiting assemblies (3) are correspondingly arranged on the wall bodies on the two sides of each wall-attached supporting seat (1); a pair of hydraulic lifting mechanisms (4A) and (4B) are fixedly arranged on two sides of each guide rail (2); the hook (41) at the movable end of each hydraulic lifting mechanism (4) is hung on the surface of the propping part (32) of the limiting component (3) far away from the ground; the movable ends of all the hydraulic lifting mechanisms (4) at the initial position are all in a retraction state;
s2: when the hydraulic climbing frame needs to be adjusted to rise upwards along a wall body, the ratchet wheel assembly (13) allows the guide rail (2) to pass upwards in one direction; the movable end of the hydraulic lifting mechanism (4A) vertically extends upwards, when the movable end passes through the adjacent limiting component (3) above, the surface of a hook (41) of the movable end abuts against the end face, close to the ground, of the abutting part (32), so that the abutting part (32) is driven to rotate relative to the surface of the limiting part (33) and abut against the surface of the limiting part, when the movable end of the hydraulic lifting mechanism (4A) vertically crosses the rotated abutting part (32), the abutting part (32) is influenced by self gravity, can automatically rotate anticlockwise and reset to an initial position, an avoiding function is realized, and then the movable end of the hydraulic lifting mechanism (4A) descends and abuts against the surface of the reset abutting part (32) again; in the process, the movable end of the hydraulic lifting mechanism (4B) does not act;
s3: taking the position of the extended movable end of the hydraulic lifting mechanism (4A) as a fulcrum, slowly lifting the fixed end of the hydraulic lifting mechanism (4A) to the position of the movable end, namely, the fixed end of the hydraulic lifting mechanism (4A) drives the guide rail (2) and the hydraulic lifting mechanism (4B) to vertically move upwards towards the direction of the movable end of the hydraulic lifting mechanism (4A), and the distance between the fixed end and the movable end of the hydraulic lifting mechanism (4A) is reduced; at the moment, the movable end of the hydraulic lifting mechanism (4B) further vertically extends outwards, namely the distance between the movable end and the fixed end of the hydraulic lifting mechanism (4B) is increased, when the distance between the movable end and the fixed end of the hydraulic lifting mechanism (4A) is minimum, the distance between the movable end and the fixed end of the hydraulic lifting mechanism (4B) is maximum, similarly, when the movable end of the hydraulic lifting mechanism (4B) extends out, the movable end passes through the surface of the abutting part (32) of the limiting component (3) adjacent to another high position and abuts against the surface of the abutting part, and at the moment, the height of the whole lifting of the hydraulic climbing frame is equal to the height difference between the two adjacent limiting components (3); in the process of rising, the distance between the movable end and the fixed end of the hydraulic lifting mechanism (4B) is reduced, the movable end of the hydraulic lifting mechanism (4A) extends upwards again, and the two hydraulic lifting mechanisms (4A) and (4B) alternately extend or retract, so that the waiting time in the process of rising is reduced; in the lifting process, the wall-attached fastener (12) and the ratchet wheel component (13) can increase the area of the contact part of the wall-attached fastener and the guide rail (2), and the lifting process is kept stable; when the hydraulic climbing frame rises to the position of the limiting component (3) with the designated height, the two hydraulic lifting mechanisms (4A) and (4B) stop alternately extending and retracting, and the movable ends of the two hydraulic lifting mechanisms (4A) and (4B) are retracted to the limit compression position;

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The technical scheme of the invention is realized as follows: as shown in fig. 1-6, in one aspect, the present invention provides an alternate lifting hydraulic climbing frame, which includes a plurality of wall-attached supporting seats 1, a guide rail 2, a limiting component 3, a hydraulic lifting mechanism 4, etc.; a walkway plate, an outer frame and a protective net are further arranged on one side of the guide rail 2 away from the wall body to form a movable space outside the wall, and the walkway plate, the outer frame and the protective net are not shown.
The wall-attached supporting seats 1 are arranged at intervals along the vertical or horizontal extending direction of the wall body and are respectively and fixedly connected with the wall body; the wall-attached support base 1 is used for limiting the moving direction of the guide rail 2.
Each guide rail 2 is respectively connected with a plurality of vertically arranged wall-attached supporting seats 1 in a sliding manner along the vertical direction; the position of the guide rail 2 is selectively locked by the wall-attached supporting seat 1; the wall attaching supporting seat 1 of the scheme can limit the motion direction of the guide rail 1 along the wall body, and when the guide rail moves reversely accidentally, the current position of the guide rail 2 is locked.
The limiting assemblies 3 are arranged on the wall bodies on the two sides of the wall-attached supporting seat 1 in pairs at intervals, and the limiting assemblies 3 are also arranged at intervals along the length extending direction of the guide rail 2; the limiting component 3 is matched with the wall-attached supporting seat 1 to limit the moving distance of the guide rail on one hand, and on the other hand, the load of the guide rail 2 and accessories thereof can be unloaded to the wall body.
The hydraulic lifting mechanisms 4 are arranged at two sides of the length extension direction of the guide rail 2 in pairs and at intervals, and the fixed ends of the hydraulic lifting mechanisms 4 are fixedly connected with the guide rail 2; the movable end of the hydraulic lifting mechanism 4 is detachably connected with the limiting component 3; because the phenomenon that the hydraulic lifting mechanism 4 and the limiting component 3 are overlapped in the vertical direction is likely to occur, in order to enable the guide rail or the hydraulic lifting mechanism 4 to vertically and smoothly lift, the abutting relation between the movable end of the hydraulic lifting mechanism 4 and the surface of the limiting component 3 can be relieved, and after the guide rail or the hydraulic lifting mechanism 4 vertically passes through the limiting component 3, the limiting component 3 can reset, and the unloading function of the guide rail 2 is recovered. The hydraulic lifting mechanism 4 comprises a movable end and a fixed end, and when the hydraulic lifting mechanism 4 moves in any direction, the movable end or the fixed end is fixed relative to the wall, and the fixed end or the movable end moves relative to the wall. The distance between the movable end and the fixed end is adjusted by the stretching of the oil cylinder of the hydraulic lifting mechanism 4.
When the distance between the movable end and the fixed end of the hydraulic lifting mechanism on one side of each wall-attached supporting seat 1 changes, the direction of the change of the distance between the movable end and the fixed end of the hydraulic lifting mechanism on the other side of the wall-attached supporting seat 1 is opposite or remains unchanged. That is, when the hydraulic lifting mechanism on the side of the wall-attached support seat 1 operates and the distance between the movable end and the fixed end increases/decreases, the hydraulic lifting mechanism on the side of the wall-attached support seat 1 either maintains the current state and does not operate; or the distance between the movable end and the fixed end of the hydraulic lifting mechanism becomes smaller/larger, and the two hydraulic lifting mechanisms 4 are in an alternative motion state.
As shown in fig. 3 to 9, the position of the movable end of the hydraulic lift mechanism 4 is limited by the stopper assembly 3, and the movable end can perform a retreating operation when passing by. Specifically, the limiting assembly 3 includes an installation portion 31, a supporting portion 32 and a limiting portion 33, the installation portion 31 is fixedly arranged on the wall, the installation portion 31 extends outwards in a direction away from the wall, one end of the installation portion 31, which is away from the wall, is provided with the supporting portion 32 and the limiting portion 33, one end of the supporting portion 32 is rotatably connected with the installation portion 31, and the other end of the supporting portion 32 extends upwards in an inclined manner in a direction away from the wall; the surface of the movable end of the hydraulic lifting mechanism 4 abuts against the surface of the abutting portion 32, and the movable end of the hydraulic lifting mechanism 4 further drives the abutting portion 32 to rotate relative to the mounting portion 31 and abut against the surface of the limiting portion 33.
As shown in fig. 7, 8 and 9, the limiting portion 33 is a vertically disposed plate-like structure, and the center of gravity of the abutting portion 32 is disposed offset from the center of the hinge shaft of the abutting portion 32 and the mounting portion 31. In a natural state, since the center of gravity of the stopper 33 deviates from the rotation axis, one end of the short axis of the stopper 33 abuts against the end face of the stopper 33; when the movable end of the vertically-raised hydraulic lifting mechanism 4 abuts against the end face of the limiting portion 33 close to the ground, the limiting portion 33 is driven to rotate until the movable end rotates clockwise to the position shown in fig. 9, and the other side surface of the abutting portion 32 abuts against the end face of the limiting portion 33, so that the movable end of the hydraulic lifting mechanism 4 can pass through smoothly without interference. In order to better contact with the abutting portion 32, a hook 41 may be further provided at the movable end of the hydraulic lift mechanism 4, the hook 41 extends toward the wall, and the hook 41 does not interfere with the abutting portion 32 that rotates clockwise to the limit position.
As an alternative to avoiding interference between the movable end of the hydraulic lift mechanism 4 and the stopper assembly 3, the hook 41 may be provided so as to be rotatable with respect to the axial direction of the hydraulic lift mechanism 4, instead of the rotatable abutting portion 32. When the hook 41 horizontally rotates by a certain angle, the position of the limiting component 3 can be avoided, and after the movable end of the hydraulic lifting mechanism 4 passes over the limiting component 3, the hook 41 is rotationally reset to realize the effect of mutual noninterference, thereby meeting the use requirement.
Because the extension length of the movable end of the hydraulic lifting mechanism 4 is limited, the distance between every two adjacent limiting assemblies 3 on the wall body along the length direction of the guide rail 2 is preferably set to be not more than the extension limit length of the movable end of the hydraulic lifting mechanism 4 relative to the fixed end, so that the hydraulic lifting mechanism 4 is safer and more reliable when moving.
As shown in fig. 3, 4, 10, 11 and 12, the wall-attached support base 1 includes a wall-attached body 11, two wall-attached fasteners 12 and a ratchet assembly 13; attach wall body 11 and wall body fixed connection, the one end symmetry that attaches wall body 11 and keep away from the wall body is provided with two and attaches wall fastener 12, two attach wall fastener 12 are relative and the interval sets up, guide rail 2 side surface symmetry is provided with the draw-in groove, two attach wall fastener 12 lock respectively in the draw-in groove and attach the one end that wall body 11 is close to ground with the surperficial sliding connection of draw-in groove and be provided with ratchet assembly 13, ratchet assembly 13's surface and guide rail 2 are close to the terminal surface roll connection of wall body, ratchet assembly 13 is selective inject the one-way moving direction of guide rail 2.
