Drawings
Fig. 1 is a front view of the present invention.
Description of reference numerals:
the device comprises a mounting plate 1, a motor 2, a positive and negative screw rod 3, a bearing seat 4, a sliding block 5, a tong arm 6, a limiting groove 7, a movable arm 8, a tong tooth 9, a mounting rack 10, an expansion rod 11, a bracket 12, a lifting ring 13 and a rubber non-slip mat 14.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, an anti-tilt lifting appliance comprises a mounting plate 1, wherein a motor 2 and a positive and negative lead screw 3 are respectively arranged on the upper surface of the mounting plate 1 and are in transmission connection, the left and right ends of the positive and negative lead screw 3 are fixed on the mounting plate 1 through a bearing seat 4, the left and right ends of the positive and negative lead screw 3 are in threaded connection with a slider 5, a clamp arm 6 is arranged below the slider 5, a limiting groove 7 is formed in the mounting plate 1, the clamp arm 6 is movably positioned in the limiting groove 7, a movable arm 8 is hinged to the bottom of the clamp arm 6, clamp teeth 9 are respectively arranged at the bottom end of the movable arm 8, a mounting frame 10 is arranged on the side surface of the clamp arm 6, and a telescopic; a bracket 12 is arranged on the mounting plate 1, and the bracket 12 is hinged with a hanging ring 13. It is specific, at first drive positive and negative lead screw 3 through starter motor 2 and rotate, drive 5 relative motion of slider when positive and negative lead screw 3 is rotatory for tong arm 6, digging arm 8 and tong teeth 9 relative motion carry out preliminary centre gripping to article, then restart telescopic link 11, make tong teeth 9 support article and press from both sides tightly, avoid article to take place to incline at the in-process that lifts, produce and rock, and lead to article to drop.
In this embodiment, rubber anti-slip pads 14 are installed on one side of the pincer teeth 9, and a gluing structure is formed between the pincer teeth 9 and the rubber anti-slip pads 14. The rubber anti-skid pad 14 increases the friction force between the rubber anti-skid pad and the object, so that the object can be stably clamped without shaking
In this embodiment, the left and right ends of the bracket 12 are hook-shaped structures for supporting the mounting plate 1 and ensuring stable connection with the mounting plate 1.
In this embodiment, spacing groove 7 is bar structure, and the thickness clearance fit of width and tong arm, and spacing groove 7 leads tong arm 6 on the one hand, and on the other hand avoids tong arm 6 to rock.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
