Abstract

A manual manhole cover lifting device comprises a grip transverse rod, a telescopic rod, a pressure handle, an axle, a roller, a support bar, an adjusting nut and a lifting hook, wherein the support bar is connected to the front of the axle, the lifting hook is disposed at the front end of the support bar through the adjusting nut, the pressure handle is connected to the rear of the axle, the telescopic rod is connected to the rear end of the pressure handle in a sleeve structure, and the transversely disposed grip transverse rod is disposed at the rear end of the telescopic rod. The pressure handle is integrally in the sleeve structure, and thereby the manual manhole cover lifting device is better in flexibility in practical use. The grip transverse rod can be pressed down to drive the pressure handle being pressed down, the pressure handle can be extended or shortened according to operating needs, the support bar drives the lifting hook hooking a manhole cover ascending for being lifted upward, and the manhole cover can be moved via the roller before being lowered slowly to complete one action of manhole cover lifting. When not in use, the manual manhole cover lifting device can be folded and stored so that the occupied space is small. The manual manhole cover lifting device is simple in structure, convenient in operation, fine in stability and high in reliability, is capable of outputting larger force by means of manual lever operating, and accordingly is more laborsaving and highly efficient in operation.

Description

A kind of manual well lid bont

Technical field

The utility model relates to a kind of urban operating mechanism inspection well well lid and promotes isolated plant, is specifically related to a kind of manual well lid bont.

Background technology

All there are facility checkout wells such as many municipal wastewaters, rainwater, combustion gas, water supply in each city, makes well lid cylinder iron at first more.Because of the cost height of ironcasting, often stolen and cause potential safety hazard, the existing cement well lids that adopt replace more.The cement well lid cost is low, and the no one steals, and long service life wants thick and heavy many but compare with casting iron well lid, and the workman is if in the inspection well during situation, take very big strength and just can open well lid, and misoperation may cause personal injury.The present invention can realize the hand hoisting of cement well lid, can be used for casting iron well lid equally.

Summary of the invention

In order to overcome the deficiencies in the prior art part, the utility model provides a kind of manual well lid bont, by the setting of lever, reaches the purpose that promotes rapid operation.

A kind of manual well lid bont described in the utility model includes grip pressure cross bar, expansion link, pressure handle, wheel shaft, roller, a handle, setting nut and suspension hook and forms.Wheel shaft is installed with the form that penetrates and is provided with roller, as subject support means of the present utility model.The outer end of wheel shaft is connected to the joint portion of handle rear end and pressure handle front end by bearing, and a handle rear end is certain angle form with the joint portion of pressure handle front end, for pressure handle press down and the upwards lifting of suspension hook leaves the space of abundance.The front of wheel shaft is connected with a handle, and the front position of a handle is provided with suspension hook by setting nut; The back of wheel shaft is connected with pressure handle.Pressure handle adopts sleeve type structure, and the rear end of pressure handle is connected with expansion link, and the rearward end of expansion link is provided with the grip pressure cross bar of horizontal form.Because pressure handle adopts sleeve type structure on the whole, so the concrete alerting ability that uses can be better.The grip pressure cross bar is pressed down, promptly drive expansion link and pressure handle presses down, pressure handle can elongate or shortens according to need of work; Drive suspension hook by a handle and tangle the well lid rising, well lid is mentioned, move well lid by roller again, slowly put down then, a well lid promotes action and finishes.Not the time spent, collapsible packing up deposited, and it is little to take up room.

A kind of manual well lid bont described in the utility model, integral structure is simple, and is easy for operation, good stability, reliability height.Use the hand lever operating mode, can export bigger power, make operation more laborsaving, efficient.

Description of drawings

Accompanying drawing 1 is the structural representation of a kind of manual well lid bont described in the utility model.1-grip pressure cross bar, 2-expansion link, 3-pressure handle, 4-wheel shaft, 5-roller 6-handle 7---setting nut 8-suspension hook.

The specific embodiment

Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: a kind of manual well lid bont described in the utility model includes grip pressure cross bar 1, expansion link 2, pressure handle 3, wheel shaft 4, roller 5, a handle 6, setting nut 7 and suspension hook 8 and forms.Wheel shaft 4 is installed with the form that penetrates and is provided with roller 5, as subject support means of the present utility model.The outer end of wheel shaft 4 is connected to the joint portion of handle 6 rear ends and pressure handle 3 front ends by bearing, and handle 6 rear end is certain angle form with the joint portion of pressure handle 3 front ends, for pressure handle 3 press down and the upwards lifting of suspension hook 8 leaves the space of abundance.The front of wheel shaft 4 is connected with a handle 6, and the front position of a handle 6 is provided with suspension hook 8 by setting nut 7; The back of wheel shaft 4 is connected with pressure handle 3.Pressure handle 3 adopts sleeve type structure, and the rear end of pressure handle 3 is connected with expansion link 2, and the rearward end of expansion link 2 is provided with the grip pressure cross bar 1 of horizontal form.Because pressure handle 3 adopts sleeve type structure on the whole, so the concrete alerting ability that uses can be better.Grip pressure cross bar 1 is pressed down, promptly drive expansion link 2 and pressure handle 3 presses down, pressure handle 3 can elongate or shortens according to need of work; Drive suspension hook 8 by a handle 6 and tangle the well lid rising, well lid is mentioned, move well lid by roller 5 again, slowly put down then, a well lid promotes action and finishes.Not the time spent, collapsible packing up deposited, and it is little to take up room.A kind of manual well lid bont described in the utility model, integral structure is simple, and is easy for operation, good stability, reliability height.Use the hand lever operating mode, can export bigger power, make operation more laborsaving, efficient.
