The vibrations will be transmitted to the wall-mounted device through the guide rail frame, increasing the burden on the wall-mounted device. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0029] See also Figure 1 and Figure 2A construction elevator wall attachment device, hereinafter referred to as the wall attachment device, includes a wall attachment seat 1 and a connecting piece, the connecting piece is a connecting arm 5, the connecting arm 5 is a square tube, the wall attachment seat 1 is fixedly installed on the shear wall by bolts, the wall attachment seat 1 is connected with a round tie rod 2 by bolts, the round tie rod 2 is connected with a main frame 3 by fasteners, the bottom of the main frame 3 is hinged with a telescopic rod 4, the other end of the telescopic rod 4 is hinged with the root of the round tie rod 2, the telescopic rod 4, the telescopic rod 4 has an inner and outer tube, the telescopic rod 4 is controlled by a nut, and then the main frame is adjusted 3 and the relative position of the round tie rod 2, thereby adjusting the length and angle of the wall attachment device, the connecting arm 5 is connected to the bent sub-plate on the standard section of the guide frame by bolts, the main frame 3 is connected to the connecting arm 5 by a Porsellier-Lipkin connecting rod mechanism 6, and a limiting structure is provided on the Porsellier-Lipkin connecting rod mechanism 6. The limiting structure can limit the rotation of the active rocker of the Porsellier-Lipkin connecting rod mechanism 6, but when the acting force is greater than the set value, the active rocker of the Porsellier-Lipkin connecting rod mechanism 6 is allowed to rotate.

[0030] Since the end of the Porcellier-Lipkin linkage 6 can only move in a straight line, when the wall-attaching device is connected to the guide rail frame, its overall length limits the lateral movement of the guide rail frame, and the longitudinal movement of the guide rail frame is limited by the limit device on the Porcellier-Lipkin linkage 6. When the longitudinal force exceeds the set value, the active rocker on the Porcellier-Lipkin linkage 6 rotates to unload the force without damaging the structure, thereby reducing the impact of vibration. Moreover, even if the limit structure fails, the wall-attaching device can still limit the horizontal shaking of the guide rail frame and exert its main function.

[0031] See also Figure 3 The limiting structure is a friction limiting member 12, which includes a friction plate 122 and a friction pair 123. The friction pair 123 is installed on the active rocker 61, and the friction pair 123 is fixedly connected with an adjusting screw 121. The adjusting screw 121 passes through the active rocker 61 and is exposed on the outside of the active rocker 61. The adjusting screw 121 is threadedly connected to the active rocker 61. The position of the friction pair 123 is adjusted by rotating the adjusting screw 121. The fixed rod 62 corresponding to the active rocker 61 is provided with a friction plate 122. When the adjusting screw 121 is tightened, the friction pair 123 is pressed against the friction plate 122 to limit the rotation of the active rocker 61 relative to the fixed rod 62. When the acting force is greater than the friction force, the active rocker 61 can rotate, and the energy of the longitudinal vibration can also be eliminated. Embodiment 2

In Embodiment 2, the limiting structure includes a steel cable 9 and a wall-attached pull rod 10. One end of the steel cable 9 is connected to the active rocker 61, and the other end is connected to the wall-attached pull rod 10. The steel cable 9 pulls the active rocker 61 obliquely upward, so that the end of the Pousselier-Lipkin linkage 6 has an upward supporting force, so that part of the longitudinal load of the guide rail frame is transmitted to the shear wall by the steel cable 9 and the wall-attached pull rod 10, thereby reducing the burden of the wall-attached device.

[0033] The wall-attached tie rod 10 includes a sleeve 101, which can be reserved in the shear wall or fixed in the shear wall by bolts after drilling. An adjusting nut 102 is provided at the end of the sleeve 101, and a tie rod 103 is threadedly connected to the adjusting nut 102. The tie rod 103 is connected to the steel cable 9.
