Abstract
A kind of reciprocating motion type chain tensioning mechanism of rock drill, its be characterized by by chain two ends respectively with stretching spring two ends be connected, driven sprocket is fixed in frame.Chain two ends are connected by the two ends of bindiny mechanism with stretching spring respectively, described bindiny mechanism is become by pull bar, nut, connecting plate, pin bank, chain two ends are fixed with pull bar respectively, and pull bar is fixed on connecting plate by nut, and upper and lower two connecting plates are connected by pin and two stretching springs.Reciprocating motion type chain tensioning mechanism compared with rock drill compares, and new structure feature of the present invention is: (1) substitute large scale, the compression spring of big rigidity with the stretching spring of small size, little rigidity；(2) driven sprocket is become fixed by floating type, improves the working environment of driven sprocket；(3) tension structure is simple, easy to adjust, laborsaving.
Description
Technical field
The invention belongs to rock drilling boring equipment chain bar clamping system manufacturing technology field, be specifically related to reciprocating motion type chain
Strainer.
Background technology
Reciprocating motion type chain tensioning mechanism advantage: (chain in use can draw more loose and more loose, logical to can compensate for tensioning
The pretightning force crossing tensioner spring compensates, and so can maintain the tensioning of chain), the field of celt rock boring the most both at home and abroad
The reciprocating motion type chain tension mode used is mostly as it is shown in figure 1,1 be frame, 2 be chain, 4 be driven sprocket, 13 be bullet
Spring pressing plate, 14 be compression spring, 9 be nut, 15 for governor motion main body, whole chain-wheel mechanism is contained in by a compression spring 14
Equipment top, regulates the rate of tension of chain by nut 9, although structure is simple, but compression spring to be born by driven sprocket
Pass to all wts of part such as the drilling tool of governor motion main body, chain, sprocket wheel and the working pulling force of chain and pretightning force, lead
Cause spring structure size is big, rigidity is also big, and spring manufacture difficulty is big, and device height about 4 meters is very inconvenient during regulation, inconvenience
In regulation control.
Summary of the invention
The reciprocating motion type chain of the rock drill that the existing rock drilling boring field that aims to overcome that of patent of the present invention uses
The shortcoming that bar strainer exists, it is provided that the reciprocal fortune of the rock drill that a kind of tensioning spring working environment is preferable, easy to adjust
Dynamic formula chain tensioning mechanism.
The technical solution adopted in the present invention is the reciprocating motion type chain tensioning mechanism of a kind of rock drill, and its main points exist
In being connected with the two ends stretching spring respectively at chain two ends, driven sprocket is fixed in frame.
Chain two ends are connected with the two ends stretching spring respectively, make spring become a part for closed loop chain, make original
The chain ring of rigidity becomes the elastic chain ring with certain rate of tension, and driven sprocket is fixed on transfixion in frame, by
Driven sprocket bears the weight of drilling tool, is not transferred to spring, and stretching spring is solely subjected to working pulling force and the pretightning force of chain, stretching
Load on spring is only the 5-10% of original compression spring, can significantly reduce spring structure size, rigidity, reduces spring and manufactures difficulty
Degree, simultaneously because spring position in impulse stroke is variable, during regulation, can be moved into correct position and be adjusted.
Chain two ends are connected by the two ends of bindiny mechanism with stretching spring respectively, and described bindiny mechanism is by pull bar, spiral shell
Mother, connecting plate, pin bank become, and chain two ends are fixed with pull bar respectively, and pull bar is fixed on connecting plate by nut, upper and lower two
Connecting plate is connected by pin and two stretching springs.
The pre-tensioning summations of two stretching springs > 2 weight chains.
Chain and stretching spring junction are positioned at the rear moving back and forth platform.
Tensioner is integrally fixed at the rear moving back and forth platform, and so regulation tension force is the most convenient, can be by platform
Move to be suitable for the position of operation, carry out tension adjusting.
Reciprocating motion type chain tensioning mechanism compared with rock drill compares, and new structure feature of the present invention is: (1)
Large scale, the compression spring of big rigidity is substituted with the stretching spring of small size, little rigidity；(2) driven sprocket is become by floating type
Fixed, improve the working environment of driven sprocket；(3) tension structure is simple, easy to adjust, laborsaving.

Detailed description of the invention
Being described in detail the present invention below in conjunction with view, cited embodiment can make the technology people of this specialty
Member more understands the present invention, but limits the present invention the most in any form.
As shown in Figure 2,3, the reciprocating motion type chain tensioning mechanism of a kind of rock drill, it is at existing reciprocating motion type
Improving on the basis of chain, be connected with the two ends stretching spring respectively at chain two ends, driven sprocket 4 is fixed in frame
1.A piece extension spring directly can be connected by connector with chain two ends, or as in Fig. 3 chain two ends pass through bindiny mechanism respectively
Being connected with the two ends of stretching spring, bindiny mechanism is made up of pull bar 5, nut 9, connecting plate 6, pin 7 etc., and chain 2 two ends are solid respectively
Surely having pull bar 5, pull bar 5 to be fixed on connecting plate 6 by nut 9, upper and lower two connecting plates 6 are by pin 7 and two stretching springs
8 connect.Adjusting nut 9, can change the spacing of upper and lower two connecting plates 6, thus change the elongation of stretching spring 8, and then
The tensioning degree of regulation chain.Spring is solely subjected to working pulling force and the pretightning force of chain, and load is only original compression spring
5-10%, depending on the pre-tensioner amount of stretching spring is typically based on the weight of chain and the rigidity of spring, two stretch the pre-of springs 9
Tensile force summation > 2 weight chains.Also can be fixed on four angles of connecting plate with four stretching springs.
The present invention is not only suitable for workpiece (such as drilling tool) 12 up-and-down movement, is also applied for and level and the most past
Multiple motion, and the reciprocating motion type chain tensioning mechanism of rock drill at any angle.Remaining not described part and prior art phase
With.
