Abstract
The utility model relates to a mechanical self-locking pipe sheet clamp comprising two groups of clamp arms. A clamp base is hinged at the lowermost ends of the clamp arms; and the uppermost ends of the clamp arms are connected to a hinging frame through a connection board. The mechanical self-locking pipe sheet clamp is characterized in that the two groups of clamp arms are L-shaped or arc-shaped; a connecting rod mechanism is arranged at the middle parts of the clamp arms; and the connecting rod mechanism is respectively hinged with the middle parts of the two groups of clamp arms through connection pieces. The mechanical self-locking pipe sheet clamp provided by the utility model has the advantages of simple structure, high security, reliability, wide application range, low manufacturing cost and the like. By utilizing the mechanical self-locking pipe sheet clamp provided by the utility model, the gravity of the pipe sheet is converted into a clamping force of the pipe sheet through the connecting rod mechanism by using the gravity of the pipe sheet; the pipe sheet is tightly clamped through four clamping boards with rubber boards; the friction force of the clamp base is improved through the rubber boards; the possibility of releasing the pipe sheet is reduced; and the production security can be improved.
Description
Technical field
The utility model relates to a kind of tunnel, subway work section of jurisdiction lifting device, is specifically related to a kind of mechanical type self-locking section of jurisdiction anchor clamps.
Background technology
Fast development along with China's city underground, and a large amount of underground constructions of various urban architecture affiliated facilities such as water, electricity, communication conduit, shield construction is fast, safe and reliable with speed of application, good engineering quality, automatically degree is high, labour intensity is low, execution conditions good, on advantages obvious to all such as the ambient environment impact are little, obtained increasingly extensive application.In shield construction, adopt the pin-connected panel pipe-plate lining.This section of jurisdiction is prefabricated forming in segment die, the section of jurisdiction at first need to moulding in segment die, solidifies to take out from segment die after reaching certain degree of hardness in steaming the oxygen kiln, and prior art generally adopts vacuum cup or hydraulic ejection, though the hydraulic ejection clamping firmly efficient is very low, seriously limited production efficiency, the vacuum cup stripping rate is fast, and efficient is high, but vacuum cup is subjected to the restriction of self, safe reliability is poor, the section of jurisdiction often occurs come off, and causes the accident.
Summary of the invention
The utility model proposes a kind of mechanical type self-locking section of jurisdiction anchor clamps for the problem that prior art exists.
The technical solution of the utility model is: a kind of mechanical type self-locking section of jurisdiction anchor clamps, comprise two groups of clip arms, clip arm is the articulated clamp seat bottom, clip arm topmost is connected on the upending frame by connecting panel, described two groups of clip arms be shaped as L shaped or arc, the middle part of clip arm is provided with connecting rod mechanism, and connecting rod mechanism is hinged with the middle part of two groups of clip arms respectively by attaching parts.
Described mechanical type self-locking section of jurisdiction anchor clamps are hinged with rotary handle at the middle part of upending frame, the affixed hook in the middle part of rotary handle, and the suspension ring of linking up with and be arranged on the connecting rod mechanism middle part consist of the self-locking mechanism of clip arm jointly.
Described mechanical type self-locking section of jurisdiction anchor clamps are installed a wear-resistant rubber sheet on the bottom surface of described clamping fixture seat.
The beneficial effects of the utility model are: 1. the utility model is simple in structure, and is safe and reliable, and applied range has the advantages such as cheap for manufacturing cost simultaneously.
2. the utility model utilizes section of jurisdiction deadweight, by connecting rod mechanism, section of jurisdiction gravity is converted to Clamping force to the section of jurisdiction, four clamping plate with rubber plate by the bottom clamp the section of jurisdiction, rubber plate has improved the friction force of clamping fixture seat, has reduced the possibility that the section of jurisdiction comes off, and has improved the safety of producing;
3. the utlity model has self-locking mechanism, self-locking mechanism can keep separating of clip arm in use, makes things convenient for the workman two groups of clip arms to be stuck in the both sides of section of jurisdiction.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the utility model clip arm clamped condition structural representation;
Fig. 3 is the utility model clip arm open configuration structural representation;
Among the figure: 1 is clip arm, and 2 is connecting rod mechanism, and 3 is upending frame, and 4 is clamping fixture seat, and 5 is rubber pad, and 6 is connecting panel, and 7 is handle, and 8 are hook, and 9 is suspension ring.
The specific embodiment
Embodiment 1: in conjunction with Fig. 1-Fig. 3, a kind of mechanical type self-locking section of jurisdiction anchor clamps, comprise two groups of L shaped clip arms, two groups of clip arms lay respectively at the both sides of connecting rod mechanism, the middle part of clip arm is hingedly fixed on the connecting rod mechanism by attaching parts, bottom handing-over at clip arm has clamping fixture seat, on the bottom surface of clamping fixture seat wear-resistant rubber sheet is installed.
The top of clip arm and upending frame are hinged through connecting panel, and an end of connecting panel is fixed on the clip arm through attaching parts, and the other end is hinged on the upending frame through attaching parts, and wherein the width of upending frame is greater than the minor increment between two clip arms; Middle part at upending frame is hinged with handle, hook of middle part welding of handle, and the suspension ring of linking up with and be arranged on the connecting rod mechanism middle part consist of the self-locking mechanism of clip arm jointly.
Embodiment 2: the part identical with embodiment 1 no longer repeats, and different is, clip arm be shaped as arc.
Principle of work: at first hook is hooked on the suspension ring, so that two clip arms separately, the hand-held upending frame of workman is aimed at the section of jurisdiction to clip arm, after being put into the position, rotary handle so that hook and suspension ring separate, is upwards mentioned suspension bracket, under the effect of connecting rod mechanism, four clamping fixture seats of clip arm can be clamped the section of jurisdiction securely.
Claims (3)
1. mechanical type self-locking section of jurisdiction anchor clamps, comprise two groups of clip arms, at clip arm articulated clamp seat bottom, clip arm topmost is connected on the upending frame by connecting panel, it is characterized in that: described two groups of clip arms be shaped as L shaped or arc, the middle part of clip arm is provided with connecting rod mechanism, and connecting rod mechanism is hinged with the middle part of two groups of clip arms respectively by attaching parts.
