Description

Portable wind-proof device for open-door crane cart

Technical Field

The utility model relates to the auxiliary field of portal cranes, in particular to a portable wind-proof device for a trolley of a luffing crane.

Background

The water inlet of the hydropower station is generally provided with a open-end crane, and is used for opening and closing a water inlet overhaul gate, and the wind-proof fixing measure of the open-end crane cart is particularly important when the open-end crane cart encounters extreme windy weather. At present, a gantry crane of a hydropower station mainly adopts a track supporting device and a ground anchor, and the two modes have the following defects:

1. the track device is driven by electrohydraulic, when the gantry crane cart works, the electrohydraulic drives the track device contact shoes to lift off the track, and after the work is finished, the springs reset the contact shoes to the track again, and the gantry crane is fixed by virtue of friction force between the contact shoes and the track. After long-time running, the return spring of the track supporting device is easy to fatigue and deform, so that the contact shoes are failed to reset or the friction force is insufficient, and the windproof grade is lowered or the windproof device is invalid;

2. the ground anchor comprises manual anchor pile and anchor hole, and anchor hole generally sets up the fixed position at cart track both ends, and the door machine cart need be opened to the position of anchor hole when the ground anchor drops down the anchor pile manually. When the gantry crane has sudden faults and cannot be repaired in a short time, the gantry crane cannot be operated to the anchor pit position, the ground anchor device cannot be put into operation, and if the gantry crane has a risk of out of control in windy weather, the gantry crane is in a large vehicle.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a portable windproof device for a trolley of a open-door crane, which can be used for temporarily and fixedly windproof the trolley of the door machine and can be quickly installed and put into operation.

In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a portable wind-proof device for open-end crane cart, includes the voussoir of setting on the track, and the voussoir is close to one side of wheel and is equipped with the arc surface of laminating with the wheel, and the voussoir both sides are equipped with the locking board, is equipped with the mounting hole that supplies the locking pull rod to pass on the locking board, and the locking pull rod locks through lock nut, and the locking pull rod lower extreme is equipped with the arm-tie of hooking the track.

In the preferable scheme, the upper side of the pull plate is provided with an anti-skid rubber layer.

In the preferred scheme, the locking pull rod lower extreme is equipped with the limiting plate, and the arm-tie one end is equipped with locking pull rod complex through-hole, and the arm-tie sets up in the limiting plate upside.

According to the portable wind-proof device for the open-end crane cart, when the ground anchor and the track supporting device cannot be used in windy weather, two groups of portable wind-proof devices are arranged on two sides of the wheels, the pulling plate is hooked on one side of the track through the fixed locking nuts, the wedge blocks are fixed, the wheels are limited by the wedge blocks, the wheels are prevented from moving, and the purpose of locking the gantry crane cart is achieved, so that the wind-proof level of the open-end crane cart is improved, and the cart is prevented from being out of control in extremely windy weather.

The utility model is further described below with reference to the accompanying drawings and examples of implementation:

FIG. 1 is a schematic view of a structure of the present utility model in a use state;

FIG. 2 is an enlarged view of FIG. 1 at A;

FIG. 3 is a schematic view of the structure of the wedge;

FIG. 4 is a schematic view of a preferred mounting structure for the pulling plate;

in the figure: wedge block 1, locking plate 2, locking pull rod 3, lock nut 4, pull plate 5, anti-slip rubber layer 6, limiting plate 7, track 8, wheel 9, arc surface 101, mounting hole 201.

Detailed Description

Example 1: as shown in fig. 1-3, a portable wind-proof device for a luffing crane cart comprises a wedge block 1 arranged on a track 8, wherein the wedge block 1 is placed on the track 8 when in use, one side of the wedge block 1, which is close to a wheel 9, is provided with an arc surface 101 attached to the wheel 9, the contact area with the wheel 9 is enlarged, the fixing stability of the wheel 9 is improved, two sides of the wedge block 1 are provided with locking plates 2, the locking plates 2 are provided with mounting holes 201 for a locking pull rod 3 to pass through, the locking pull rod 3 is locked through locking nuts 4, the locking nuts 4 are arranged on the upper side of the locking plates 2, the lower end of the locking pull rod 3 is provided with a pull plate 5 for hooking the track 8, and the pull plate 5 is hooked on one side of the track 8.

When the anti-wind device is specifically used, under the condition of strong wind weather, when the open-end crane cart fails and cannot be repaired in a short time, the ground anchor cannot be put into, and when the wind-proof grade of the return failure of the trolley is lowered or fails, two groups of portable wind-proof devices are installed on two sides of the wheel 9, the arc surface 101 of the wedge block 1 is attached to the tread of the wheel 9, the locking pull rod 3 penetrates into the installation hole 201 from the lower part, the orientation of the pull plate 5 is adjusted in the penetrating process, the end part of the locking pull rod is located in the grooves on two sides of the track 8, the pull plate 5 is hooked on one side of the track 8 through the fixed locking nut 4, the fixing of the wedge block 1 is completed, the wedge block 1 limits the wheel 9, the wheel 1 is prevented from moving, the locking gantry crane cart is achieved, the wind-proof grade of the open-end crane cart is improved, and the extremely strong wind down cart is prevented from being out of control.

Example 2: unlike the embodiment 1, as shown in fig. 4, the pull plate 5 is provided with an anti-slip rubber layer 6 at the upper side. Through setting up anti-skid rubber layer 6, when lock nut 4 locking, when upwards pulling up locking pull rod 3, the in-process of track 8 is hooked to arm-tie 5 compresses anti-skid rubber layer 6, helps improving arm-tie 5 and track 8's hooking power, improves frictional force simultaneously, is favorable to improving the installation steadiness of voussoir 1.

Preferably, the lower extreme of locking pull rod 3 is equipped with limiting plate 7, and arm-tie 5 one end is equipped with the through-hole with locking pull rod 3 complex, and arm-tie 5 can rotate along locking pull rod 3, and arm-tie 5 sets up in limiting plate 7 upside.

During the use, need not dismantle lock nut 4, only need loosen the back with lock nut 4, adjust the downward extension length of locking pull rod 3, rotate the arm-tie 5 to one side of keeping away from track 8, the arm-tie 5 does not influence the placing of voussoir 1 this moment, place voussoir 1 back on the track, rotate the arm-tie 5, with its one end of keeping away from locking pull rod 3 turn to track 8 one side, then screw up lock nut 4, make arm-tie 5 hook tight track.

Therefore, the installation can be realized without completely disassembling the pull plate 5, the locking pull rod 3 and the locking plate 2, parts are prevented from being lost easily after the locking pull rod 3 and the locking nut 4 are separated, and meanwhile, the disassembly and assembly efficiency is improved.
