Background art:
the multifunctional crown block is one of key devices designed and manufactured for meeting the production requirements of an electrolytic workshop of an electrolytic aluminum plant. The multifunctional crown block is provided with a group of wrench mechanisms which are specially designed for assembling and disassembling the box-type clamp, and in the process of replacing the anode of the multifunctional crown block, the box-type clamp on the anode guide rod of the electrolytic cell needs to be unscrewed by a wrench through an oil cylinder control system, and the bolt head of the box-type clamp is lifted into the wrench screwing head to prevent the box-type clamp from falling.
At present at multi-functional overhead traveling crane pole changing during operation, multi-functional overhead traveling crane spanner is unscrewed behind the box-type fixture, need whole the box-type fixture of carrying to carry out other operations, only lean on overhead traveling crane spanner to screw the inside screw thread of head and the bolt head cooperation of box-type fixture to carry out the clamping and hardly make box-type fixture remain firm always at this in-process, lead to box-type fixture to drop to ground easily, cause equipment damage or even personnel to receive risks such as injury, have very big potential safety hazard.
The utility model has the following contents:
an object of the utility model is to provide an anti falling device for multi-functional overhead traveling crane utilizes simple mechanical principle to realize the reinforcement protection to box-type fixture.
The utility model discloses by following technical scheme implement: an anti-falling device for a multifunctional crown block comprises a clamping hook, a fixing frame and a supporting plate, wherein the clamping hook is rotatably arranged on a wrench base; the wrench is characterized in that a fixing frame fixedly connected with a cylinder body of the oil cylinder is arranged right above the supporting plate, the bottom end of the fixing frame is in movable contact with the supporting plate, and the head of the clamping hook is movably arranged below the wrench base.
Preferably, the bottom of the fixing frame is rotatably provided with a roller.
Preferably, the anti-falling device comprises two hooks, and the two hooks are respectively rotatably arranged on two sides of the wrench base.
Preferably, the two hooks are fixed by a connecting rod.
The utility model has the advantages that: the utility model discloses utilize mechanical principle, at the in-process that the hydro-cylinder of multi-functional overhead traveling crane returns and contracts, mount and backup pad butt, and then control the trip head and rotate towards spanner mechanism, block through the trip and embrace and keep firm box-shaped fixture, and then effectively avoided box-shaped fixture to take place the possibility that drops during multi-functional overhead traveling crane removes the operation, stopped the potential safety hazard.
Description of the drawings:
FIG. 1 is a schematic view of the overall structure of the middle hook of the present invention when the middle hook does not clasp the box-type clamp;
fig. 2 is a schematic view of the overall structure of the middle hook clamp when the box-shaped clamp is embraced by the middle hook clamp.
In the figure, 1 is a clamping hook, 2 is a supporting plate, 3 is a spring, 4 is a wrench machine seat, 5 is an oil cylinder, 6 is a cylinder body, 7 is a piston rod, 8 is a fixing frame, 9 is a roller, 10 is a connecting rod, 11 is a box-type clamping apparatus, and 12 is a lifting lug.
The specific implementation mode is as follows:
the invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, an anti-dropping device for a multifunctional crown block comprises a hook 1, a fixing frame 8 and a supporting plate 2, wherein the hook 1 is rotatably arranged on a wrench base 4, the head of the hook 1 is movably arranged below the wrench base 4, the supporting plate 2 is fixed on the side wall of the hook 1 at one side of the wrench base 4, a spring 3 is connected between the supporting plate 2 and the wrench base 4, the spring 3 plays a stretching role on the hook 1 through the supporting plate 2, and when the spring 3 is in a normal state, the head of the hook 1 can be stretched to one side of the wrench base 4 through the supporting plate 2, so that the wrench mechanism can be normally used; a fixing frame 8 fixedly connected with a cylinder body 6 of the oil cylinder 5 is arranged right above the supporting plate 2, the bottom end of the fixing frame 8 is movably contacted with the supporting plate 2, the wrench machine base 4 is driven to move upwards in the retracting process of a piston rod 7 of the oil cylinder 5, so that the supporting plate 2 is contacted with the bottom end of the fixing frame 8, and in the continuing retracting process, the fixing frame 8 presses the supporting plate 2 downwards, so that the head of the clamping hook 1 is controlled to rotate to the lower side of the wrench machine base 4 to clamp and support a box-type clamping device on the wrench mechanism; the bottom of the fixed frame 8 is rotatably provided with a roller 9, and the fixed frame 8 is in movable contact with the supporting plate 2 through the roller 9 so as to reduce the friction force when the fixed frame 8 is in contact with the supporting plate 2 and avoid abrasion;
the anti-falling device for the multifunctional crown block comprises two clamping hooks 1, wherein the two clamping hooks 1 are respectively and rotatably arranged on two sides of a wrench machine base 4, and the two clamping hooks 1 are used for simultaneously supporting the box-type clamping device, so that two-point support is realized, and the support is more stable; the two hooks 1 are fixed through the connecting rod 10, and synchronous movement of the two hooks 1 can be realized through fixation of the connecting rod 10.
When the multifunctional crown block is used for anode replacement operation, the piston rod 7 of the oil cylinder 5 moves downwards to drive the wrench base 4 to move downwards, at the moment, the fixed frame 8 does not contact the supporting plate 2, and the clamping hook 1 is far away from the position right below the wrench base 4 under the action of the spring 3, so that the wrench base 4 is prevented from being influenced to operate; after the box-type fixture 11 is completely loosened by the wrench mechanism on the wrench machine base 4, the piston rod 7 of the oil cylinder 5 retracts to drive the wrench machine base 4 to retract upwards, after the piston rod 7 retracts to a specified position, the fixing frame 8 contacts and presses the supporting plate 2, the supporting plate 2 rotates downwards to elongate the spring 3, the head of the clamping hook 1 is driven to rotate to the position below the wrench machine base 4 through rotation, the lifting lug 12 of the box-type fixture 11 is hooked, the box-type fixture 11 is clamped in the anti-falling device, and therefore the box-type fixture 11 is kept stable.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
