Technical field
The utility model relates to a kind of high position boring servicing unit of facing upward.
Background technology
In the building decoration engineering, have the operation at some ceiling tops, the installation such as furred ceiling, ventilation shaft, electric, fire-fighting etc., all these need face upward the aperture that bores some to ceiling.The high position boring of facing upward at present is to take some scaffolds mostly, the workmen puts on the shelf and constructs, and this traditional method of work efficient is very low and labour intensity is big again, also with certain security risk, this present situation is got a new look, and improving equipment and process means is the only way out.
Summary of the invention
The utility model provides a kind of high position boring servicing unit of facing upward.By this device the boring work of facing upward that originally just can finish is converted to ground handling on scaffold, simplified the operation content, alleviated labour intensity, improved operating efficiency, and reduced security risk.
In order to address the above problem, the utility model is achieved through the following technical solutions, and it is by electric hammer, holder, stop screw, handle, lower fulcrum bar, power line, hydraulic pressure lifting device, and mechanical elevating seat, steel ball, handwheel, upper rack posts, armful lobe are formed.Wherein hydraulic pressure lifting device is an independently roughing feed system, is made up of large tank, stop valve, oil sump, check valve, small oil tank, depression bar, is responsible for the lifting of device; Upper rack posts, handwheel, steel ball, mechanical elevating seat are then formed a little feed system, are responsible for the advance and retreat of drill bit.Its structural principle of hydraulic pressure lifting device and jack roughly the same, large tank adopts the more piece cylinder here, to increase this device institute applicable scope.Holder is the metal rigidity part, and shape does not have strict demand, should determine its shape and size according to selected electric hammer, is advisable electric hammer being fixedly secured with an armful lobe, and an end of holder is established the axle sleeve fixed with upper rack posts.Upper rack posts is that an end is established externally threaded pipe, and a fixing handle is adorned in the appropriate location of upper rack posts, is obstructed moment loading during with the work of restriction electric hammer and rotates; The end of thread of upper rack posts screws in a handwheel, and handwheel is a spoke structure, and the centre is a cylinder, and cylindrical center establishes the internal thread with the upper rack posts coupling, and cylindrical is established an annular groove.The mechanical elevating seat is cylindric, establishes stepped hole, packs into behind the upper rack posts screw-in handwheel in the mechanical elevating seat hole, makes the handwheel face of cylinder and stepped hole matched in clearance; Be provided with the steel ball that reduces friction between the contact-making surface of handwheel cylinder end face and step, a mechanical elevating seat screw of limiting at handwheel cylinder annular groove place is with the axial displacement of restriction handwheel and mechanical elevating seat.The other end of mechanical elevating seat is by pin and lower fulcrum bar strong bonded; The other end of lower fulcrum bar firmly is connected with hydraulic pressure lifting device.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is the utility model hydraulic pressure lifting device schematic diagram (propradation).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Among the figure 1, electric hammer; 2, holder; 3, stop screw; 4, handle; 5, lower fulcrum bar; 6, power line; 7, hydraulic pressure lifting device (wherein: 7.1 large tanks, 7.2 stop valves, 7.3 oil sumps, 7.4 check valves, 7.5 small oil tanks, 7.6 depression bars); 8, pin; 9, mechanical elevating seat; 10, steel ball; 11, handwheel; 12, upper rack posts; 13, embracing lobe forms.Hydraulic pressure lifting device [7] is made according to pascal's principle, its structure and jack are roughly the same, close stop valve [7.2], shake depression bar [7.6] gently, under the effect of check valve [7.4], small oil tank [7.5] is pumped from oil sump [7.3] and is injected large tank [7.1], and large tank [7.1] ejects piston along with the increase of oil; Open stop valve [7.2], the oil in the large tank [7.1] is put back to then piston falling of oil sump [7.3].In view of the work characteristics of this device will be with lifting travel size and rising or falling speed speed as the major technology index, so large tank [7.1] adopts the more piece cylinder, to increase this device institute applicable scope, and the ratio of piston cross-section is unsuitable excessive between large tank [7.1] and small oil tank [7.5], otherwise influences rising or falling speed.Holder [2] is the metal rigidity part, and shape is determined according to selected electric hammer [1], establishes some apertures on holder [2], with an armful lobe [13] electric hammer [1] is fixedly secured to get final product; One end of holder [2] is established and the fixed axle sleeve of upper rack posts [12].Upper rack posts [12] is that an end is established externally threaded pipe, a fixing handle [4] is adorned in the appropriate location of upper rack posts [12], the time be obstructed moment loading and rotate in order to restriction electric hammer [1] work, the end of thread of upper rack posts [12] screws in the internal thread in the middle of the handwheel [11], and the cylindrical of handwheel [11] centered cylinder is established an annular groove.Mechanical elevating seat [9] is cylindric, establishes stepped hole, packs into behind upper rack posts [12] the screw-in handwheel [11] in mechanical elevating seat [9] hole, and making handwheel [11] face of cylinder and stepped hole is matched in clearance; Between the contact-making surface of handwheel [11] cylinder end face and mechanical elevating seat [9] step, be provided with the steel ball [10] that reduces friction, mechanical elevating seat [9] screw [3] of limiting at handwheel [11] cylinder annular groove place is with the axial displacement of restriction handwheel [11] with mechanical elevating seat [9].The other end of mechanical elevating seat [9] is by pin [8] and lower fulcrum bar [5] strong bonded; The other end of lower fulcrum bar [5] firmly is connected with hydraulic pressure lifting device [7].In addition, the power line [6] and the thread switching control of electric hammer [1] are introduced ground, to realize the operation on ground.
During use, the utility model is upright, shake depression bar lifting device height, allow the drill bit of electric hammer touch bore position, start then, the speed of boring feeding then realizes by the speed of rotation hand wheel.During adjacent borehole, regulate the discrepancy in elevation with handwheel and can move the position.During shutdown, turn on stop valve, hydraulic pressure lifting device is operated very simple just from horizontal reset.
