Abstract
The utility model relates to an anti-dropping device of a lifting system, which is mainly formed by a guide rail and a steel beam. The steel beam is horizontally arranged at the top end of a lifting platform. A steel groove formed by a first square steel bolt and a second square steel bolt is arranged on the steel beam and is vertically inserted into the guide rail. A circular steel bolt used for hanging a steel wire rope penetrates through the steel beam. Corner rope pads used for penetrating the steel wire rope to tie the entire lifting platform are installed at the four corners of the lifting platform. A spring device is arranged at the bottom of the lifting platform. The utility model has the advantages that when the lifting platform is out of control suddenly and drops down, the heavier of the weight of the lifting platform is, the larger the clamping force between the first square steel bolt and the second square steel bolt and the guide rail is, the lifting platform is ensured not to drop down and the safety of personnel and properties is effectively guaranteed.

Described spring installation is made up of a spring, spring bumper cover, spring spool, one end and the spring bumper cover of this spring are connected and fixed, its other end and spring spool roof are connected and fixed, and spring bumper cover is interspersed in the fluting on the spring housing barrel, also has second fluting that is used for interting steel rope on this spring housing barrel.
Be the plane between the described first square bar bolt and the second square bar bolt and the guide pass and 45 ° placement be installed.
The end that described girder steel is close to the lifting table top is 30 ° upwards, and the last end face of girder steel is the level of state.
Circular steel bolt on described girder steel shape triangular in shape distributes.
Described lifting table is equipped with and the contacted coil tension spring of girder steel near on the top of guide rail one side.
A clip slot that is used for fixing girder steel is installed on the described lifting table.
The effect that the utility model is useful: the utility model is a kind of improvement to prior art, when the unexpected tenesmus out of control of lifting table, its weight is heavy more, the power of being blocked between the first square bar bolt and the second square bar bolt and the guide rail is then big more, then facilitate thus and guarantee that lifting table does not cause tenesmus, thereby actv. has guaranteed the safety of personnel, property.

The specific embodiment
Label in the accompanying drawing is: 1, guide rail, 2, girder steel, 3, lifting table, 4, the first square bar bolt, 5, the second square bar bolt, 6, steel tank, 7, steel rope, 8, the circular steel bolt, 9, the corner paunch mat, 10, spring installation, 11, spring, 12, spring bumper cover, 13, spring spool, 14, first fluting, 15, second fluting, 16, coil tension spring, 17, clip slot.
Below in conjunction with drawings and Examples the utility model is described further:
As shown in Figure 1: the utility model mainly (divides single track and double track by effect or structure by guide rail 1, single track is applied mechanically accompanying drawing 3 ways, double track is applied mechanically accompanying drawing 2 ways) jacking system formed is prerequisite, girder steel 2 is lain in a horizontal plane in the top of lifting table 3, and a steel tank that is formed by the first square bar bolt 4 and the second square bar bolt 5 is arranged on this girder steel 2, and vertically be inserted in the described guide rail 1, be connected with guide rail 1 and the first square bar bolt 4 and the second square bar bolt 5 and 1 on guide rail have certain clearance, and be the plane between the first square bar bolt 4 and the second square bar bolt 5 and guide rail 1 facade and install for 45 ° and place.The first square bar bolt 4 and the second square bar bolt 5 can be made the abutted surface (as associated shape such as circular arc, circles) that meets guide rail 1 outer shape by guide rail 1 one sides, be interspersed with the circular steel bolt 8 of hanging steel rope 7 as being on this girder steel 2, four angles of described lifting table 3 are equipped with one and are used to the corner paunch mat 9 that reeve 7 hitches whole lifting table 3.The effect of this corner paunch mat 9 is to prevent to rub between steel rope 7 and 3 four angles of lifting table, thereby causes steel rope 7 fractures.Described lifting table 3 is equipped with and girder steel 2 contacted coil tension springs 16 near on the top of guide rail 1 one sides, and the power of this coil tension spring bounce-back can be upspring an end of girder steel 2 and is advisable, so that should end unlikely level when lifting table 3 tenesmus descend.A clip slot 17 that is used for fixing girder steel 2 also is installed on this lifting table 3.
As shown in Figure 4: the bottom of this lifting table 3 is equipped with a spring installation 10.Described spring installation 10 is made up of a spring 11, spring bumper cover 12, spring spool 13, one end and the spring bumper cover 12 of this spring 11 are connected and fixed, its other end and spring spool 13 roofs are connected and fixed, and spring bumper cover 12 is interspersed in the fluting of first on spring spool 13 walls 14.Also have second fluting 15 that is used for interting steel rope 7 on these spring spool 13 walls, steel rope 7 is connected together mutually with the bottom surface of spring bumper cover 12 thus.The purpose of this device is to play the buffer action in the lifting table 3 unexpected tenesmus processes.
Specific embodiment: when lifting table 3 is done oscilaltion, girder steel 2 also simultaneously along with lifting table 3 along guide rail 1 direction vertical lift, as because faults such as artificial or machinery when causing lifting table 3 tenesmus suddenly, the steel rope 7 that ties up on the lifting table 3 is passed to circular steel bolt 8 on the girder steel 2 with power, cause on the girder steel 2 is to hang steel rope 7 one ends at first by toward drop-down a bit of distance the time, owing to first square bar bolt 4 on the girder steel 2 that possesses certain strength and stiffness and the rightabout application force of the second square bar bolt, 5 generations, make the gap of 1 on the original first square bar bolt 4 and the second square bar bolt 5 and guide rail after closure, block guide rail 1 inflexibly, and the weight of lifting table 3 is heavy more, the power of being blocked is then big more, with this then facilitate and guarantee lifting table 3 do not cause the tenesmus, thereby actv. has guaranteed personnel, the safety of property.
