Description
Technical field
The utility model belongs to the anti-silt formula wheel safety hook in the protective gear field of building operations, particularly a kind of attachment type raise scaffold.
Background technology
Attachment type raise scaffold refers to be set up certain altitude and is attached in engineering structures, rely on self jacking equipment and device, can successively climb with engineering structures or decline, there is the external scaffolding of overturn-preventing, falling proof device, be widely used in middle-high building.Attachment type raise scaffold is primarily of formations such as attached lift scaffold frame structure, adhering lifting seat, anti-tilt device, falling proof device, elevating mechanism and control device.Wherein said falling proof device, that if electric block chain ruptures, then scaffold can drop down for scaffold in lifting or decline process, the situation design that may cause casualties, falling proof device can be used to the usage safety performance improving attachment type raise scaffold.
Existing falling proof device can be divided into according to the difference of structure: balancing point type fall-preventing device, wheel safety hook, swing block type catching device.Wherein wheel safety hook safety factor is the highest, is subject to consistent favorable comment at the construction field (site).But in the work progress of building site, there is the situation that a large amount of silt and protection water can be unrestrained downwards, inside the falling proof device inevitably entering into scaffold, especially obvious with wheel safety hook.Wheel safety hook, once pour into silt, will have a strong impact on the normal rotation of runner, not have due anti-fall effect, can bring very large potential safety hazard to construction safety.
Utility model content
Applicant is in building operations operation for many years, find the problems referred to above, through exploring and research, object is the anti-silt formula wheel safety hook providing a kind of attachment type raise scaffold, can effectively prevent the silt that comes down in torrents and protection water from pouring into the inner chamber of wheel safety hook, thus guarantee the braking effect that catching device remains excellent, improve the usage safety performance of attachment type raise scaffold.
The utility model is for solving its technical problem, the technical scheme taked is the anti-silt formula wheel safety hook of a kind of attachment type raise scaffold of design, and its structure comprises: bearing, back shaft, runner, anti-fall guide rail, ratchet, ratchet, seal groove and sealing ring; Described roller centre is provided with axis hole, and runner is set on back shaft rotationally by axis hole, and the two ends of described back shaft are fixed on bearing; Described anti-fall guide rail is provided with vertical spaced anti-fall slotted eye, in the outer rim of described runner, along radial spoke injection 4-6 anti-fall inserted block of runner, and 4-6 anti-fall inserted block is equally distributed along the circumference of runner, and described anti-fall inserted block inserting is in anti-fall slotted eye; Described ratchet is opened in the axis hole of runner, and ratchet is coaxial with runner, back shaft offers jack, the tail end inserting of described ratchet is in jack, described ratchet and ratchet form the ratchet mechanism of internal messing jointly, in the left and right sides of runner, be also respectively arranged with a seal groove coaxial with runner, described sealing ring is arranged in seal groove.
Preferably, the quantity of described anti-fall inserted block is preferably 5.
The utility model have employed technique scheme, by after this new application is on attachment type raise scaffold, ratchet mechanism according to its internal messing does the characteristic of one-way movement, effectively can brake, prevent falling accident from occurring when scaffold accidental falling to scaffold, particularly this novel wheel-type catching device, also be provided with sealing device, i.e. seal groove and sealing ring, sealing ring can be fixed on the two sides of runner by seal groove, effective sealing has been carried out in the gap formed between back shaft and runner and cavity by sealing ring, so, the silt come down in torrents in a large number in building operations and protection water can not enter and be deposited in the gap and cavity that are formed between back shaft and runner, and then interference cannot be formed to the ratchet mechanism of the main brake component-internal messing of catching device, ratchet and ratchet can maintain long-term proper engagement and move, therefore the anti-silt formula wheel safety hook of this Novel attached lifting scaffold can in severe building operations environment, the normal running status of long-term maintenance, guarantee the safety of construction environment, be adapted at various building site to apply.

Detailed description of the invention
Be further described this novel structure below in conjunction with the drawings and specific embodiments, its structure and advantage will clearly.
Referring to Fig. 1-6, a kind of anti-silt formula wheel safety hook of attachment type raise scaffold, its structure comprises: bearing 1, back shaft 2, runner 3, anti-fall guide rail 4, ratchet 5, ratchet 6, seal groove 7 and sealing ring (not shown); Described runner 3 center is provided with axis hole 8, and runner 3 is set on back shaft 2 by axis hole 8 rotationally, and the two ends of described back shaft 2 are fixed on bearing 1; Described anti-fall guide rail 4 is provided with vertical spaced anti-fall slotted eye 9, in the outer rim of described runner 3, along radial spoke injection 4-6 anti-fall inserted block 10 of runner 3, and 4-6 anti-fall inserted block 10 is equally distributed along the circumference of runner 3, the quantity of anti-fall inserted block 10 is preferably 5, and the inserting of described anti-fall inserted block 10 is in anti-fall slotted eye 9; Described ratchet 5 is opened in the axis hole 8 of runner 3, and ratchet 5 is coaxial with runner 3, back shaft 2 offers jack 11, tail end 6 inserting of described ratchet is in jack 11, described ratchet 5 and ratchet 6 form the ratchet mechanism of internal messing jointly, in the left and right sides of runner 3, be also respectively arranged with a seal groove 7 coaxial with runner 3, described sealing ring is arranged in seal groove 7.
At the construction field (site), sealing ring can be fixed on the two sides of runner 3 by the seal groove 7 that this Novel anti-falling device adopts, effective sealing has been carried out in the gap formed between back shaft 2 and runner 3 and cavity by sealing ring, so, the silt come down in torrents in a large number in building operations and protection water can not enter and be deposited in the gap and cavity that are formed between back shaft 2 and runner 3, and then interference cannot be formed to the ratchet mechanism of main brake component-internal messing, give the condition that ratchet 5 ratchet 6 maintains the motion of long-term proper engagement, therefore the anti-silt formula wheel safety hook of this Novel attached lifting scaffold can in severe building operations environment, the normal running status of long-term maintenance, guarantee the safety of construction environment, be adapted at various building site to apply.
