Description

Technical Field

[0001] The utility model belongs to the technical field of arch frame installation equipment, and in particular relates to an electromagnetic suction cup claw clamp with power-off protection. Background Art

[0002] When the arch frame is installed, it is generally assisted by an arch frame trolley. The main arm of the arch frame trolley is generally equipped with a mounting frame for supporting the arch frame through an adjusting seat. Generally, a telescopic drive, a first electromagnetic suction cup, and a second electromagnetic suction cup are arranged on the left and right ends of the mounting frame. The first electromagnetic suction cup and the second electromagnetic suction cup are in contact with the front and rear side walls and the bottom of the arch frame respectively. However, it does not have a protective structure for preventing the arch frame from moving out of position or sliding down when the first electromagnetic suction cup and the second electromagnetic suction cup are powered off. Therefore, in actual use, when the first electromagnetic suction cup and the second electromagnetic suction cup are powered off, that is, the first electromagnetic suction cup and the second electromagnetic suction cup do not have the function of adsorbing the arch frame, then the arch frame is easy to move out of position relative to the mounting frame or slide down along the mounting frame, and the safety is poor.

DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] like Figure 1-4 As shown, an electromagnetic suction cup claw clamp with power-off protection includes a mounting frame 1 for placing an arch frame, two electromagnetic suction cup assemblies respectively arranged at both ends of the mounting frame 1, and a plurality of reinforcement assemblies for protecting the arch frame when the electromagnetic suction cup assemblies are powered off are arranged on the mounting frame 1 between the two electromagnetic suction cup assemblies;

[0024] The reinforcement component includes a vertical support plate 5 arranged at the bottom of the mounting frame 1, an outer protective frame 7 connected to the mounting frame 1 and arranged outside the vertical support plate 5, two screw rods 8 symmetrically arranged on the front and rear sides of the vertical support plate 5, a nut seat 9 connected to the screw rod 8 through a ball nut pair, a side positioning clamping plate 10 detachably connected to the nut seat 9 and used to clamp the arch frame, and a power component used to drive the two screw rods 8 to rotate so that the two nut seats 9 move toward or away from each other at the same time. The screw rod 8 is rotatably connected to the vertical support plate 5 and the outer protective frame 7.

[0025] Preferably, the electromagnetic suction cup assembly includes two electric telescopic parts 2 fixed on the mounting frame 1, an electromagnetic suction cup 1 3 and an electromagnetic suction cup 2 4 arranged at the telescopic ends of the electric telescopic parts 2, the telescopic ends of the two electric telescopic parts 2 are facing opposite directions, the two electromagnetic suction cups 1 3 are located between the two electromagnetic suction cups 2 4, and the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered by a battery, which can be placed in the mounting frame 1.

[0026] It should be noted that, in this embodiment, the electric telescopic member 2 is an electric telescopic push rod.

[0027] Preferably, the two side positioning clamping plates 10 are provided with a bottom positioning support plate 17 for supporting the bottom of the arch frame on one side opposite to the other side. When the two side positioning clamping plates 10 clamp the arch frame, the two bottom positioning support plates 17 are in contact with the front and rear side walls of the mounting frame 1 on the sides away from the side positioning clamping plates 10 respectively.

[0028] The side positioning clamping plate 10 clamps and the bottom positioning support plate 17 supports the arch frame to achieve the protective effect of limiting and reinforcing the arch frame after the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered off. After the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered off, the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 have no adsorption effect on the arch frame, which causes the arch frame to easily move and dislocate relative to the mounting frame 1 or slide down along the mounting frame 1. In the utility model, the bottom positioning support plate 17 can be used to support the bottom of the arch frame, and the front and rear sides of the arch frame can be clamped and limited by the side positioning clamping plate 10, so that the arch frame is not easy to move and dislocate relative to the mounting frame 1 or slide down along the mounting frame 1, thereby achieving the protective effect of limiting and reinforcing the arch frame after the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered off.

[0029] Preferably, the upper end surface of the side positioning clamping plate 10 is lower than the upper end surface of the arch frame, and the upper end surface of the side positioning clamping plate 10 will not contact the surrounding rock of the cave body, which facilitates the installation of the arch frame.

[0030] Preferably, a groove body 6 is opened on the vertical support plate 5, and the power assembly includes a rotating shaft 12 rotatably connected to the inside of the groove body 6, a bevel gear 13 sleeved on the rotating shaft 12, two bevel gears 14 respectively sleeved on two screw rods 8 and meshing with the bevel gear 13, and a servo motor 11 connected to one end of the rotating shaft 12.

[0031] It should be noted that, in the present embodiment, the threads of the two screw rods 8 have the same rotation direction, the servo motor 11 drives the rotating shaft 12 and the bevel gear 1 13 to rotate, and then the bevel gear 1 13 can drive the two bevel gears 2 14 and the screw rod 8 to rotate, and the rotation directions of the two screw rods 8 are opposite, then, the threads of the two screw rods 8 have the same rotation direction, then the two nut seats 9 can move toward each other at the same time to clamp the mounting frame 1, or the two nut seats 9 can move away from each other at the same time to loosen the mounting frame 1.

[0032] Preferably, a limiting slider 15 is provided on the nut seat 9, and a limiting groove 16 for the limiting slider 15 to slide is opened on the inner wall of the outer protective frame 7. The limiting slider 15 slides in the limiting groove 16, thereby limiting the movement of the nut seat 9, so that the nut seat 9 can move along the screw rod 8.

[0033] When in use, place the arch frame on the top of the mounting frame 1, then start the electric telescopic member 2, and move the telescopic end of the electric telescopic member 2 to make the two electromagnetic suction cups 1 3 approach each other and the two electromagnetic suction cups 2 4 approach each other, and through the adsorption effect of the two electromagnetic suction cups 1 3 and the two electromagnetic suction cups 2 4, the arch frame is stably placed on the top of the mounting frame 1, and then start the servo motor 11. The servo motor 11 will drive the rotating shaft 12 and the bevel gear 1 13 to rotate, and the rotation of the bevel gear 1 13 will drive the two bevel gears 2 14 meshing with it to rotate, so that the two screw rods 8 rotate. At this time, the two screw rods 8 rotate in opposite directions, but because the thread rotation directions of the two screw rods 8 are the same, the two nut seats 9 can move towards each other, and the movement of the two nut seats 9 will drive the two side positioning clamping plates 10 The arch frame moves toward each other, the arch frame is clamped by two side positioning clamping plates 10, the bottom of the arch frame is supported by two bottom positioning support plates 17, and the arch frame is pressed and reinforced toward the mounting frame 1 by the side positioning clamping plates 10 and the bottom positioning support plates 17, so that after the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered off, that is, when the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 have no adsorption effect on the arch frame, the arch frame can also be clamped by the side positioning clamping plates 10 and supported by the bottom positioning support plates 17, and the arch frame is pressed and reinforced toward the mounting frame 1 by the side positioning clamping plates 10 and the bottom positioning support plates 17, so as to form a protective effect of limiting and reinforcing the arch frame, so that the arch frame is not easy to move out of place or slide down along the mounting frame 1, forming power-off protection for the arch frame when the electromagnetic suction cup 1 3 and the electromagnetic suction cup 2 4 are powered off.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
