For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of counterweight that is used for elevator, comprise counterweight frame, counterweight iron pressing plate and counterweight iron, this counterweight frame comprises two roofs rail, two Li Liang and two following side bars, two upright beams are parallel to each other, two roof rail secured in parallel are connected the top of two upright beams, two following Liangping row are fixedly connected on the lower end of two upright beams, it is characterized in that
A) also comprise short Li Liang and horizontal arm-tie, this horizontal arm-tie is fixedly connected between two upright beams; This short upright beam between two upright beams, and with upright Liangping row; The bottom of short upright beam is fixedly connected on two following side bars, captives joint with horizontal arm-tie in the top;
B) described counterweight iron is embedded between upright beam and short upright beam;
C) described counterweight iron pressing plate is two, is mobily connected in respectively between upright beam and the short upright beam, and is positioned at the upper end of counterweight iron.
The described counterweight that is used for elevator also comprises two anti-drop blocks, and symmetry is fixedly connected on the side of upright beam respectively.
Compared with prior art, adopt the advantage of technique scheme to be:
1. elevator is under the situation of high-speed cruising, and the counterweight iron pressing plate still can be firm pushes down counterweight iron, easy to adjust.Compared with prior art, the technical program has been set up short Li Liang and horizontal arm-tie, and this horizontal arm-tie is fixedly connected between two upright beams; This short upright beam is between two upright beams.Like this, about whole counterweight is divided in two counterweight supports.Counterweight iron be embedded to respectively about in two counterweight supports.The counterweight iron pressing plate also is two, pushes down the counterweight iron in the counterweight support respectively, and steadiness strengthens.Simultaneously, adopt two-row structure, can provide the enough intensity and the counterweight iron of space placement suitable quantity, the convenient adjusting.
2. can prevent effectively that counterweight iron breaks away from counterweight.Compared with prior art, also comprise two anti-drop blocks in the technical program, symmetry is fixedly connected on the side of upright beam respectively, can reduce because vibrations cause the risk that pouring weight is come off.

Among the figure, 1, the counterweight iron pressing plate, 2, counterweight iron, 3, roof rail, 4, Li Liang, 5, side bar down, 6, short upright beam, 7, horizontal arm-tie, 8, anti-drop block, 801, substrate, 802, baffle plate, 803, " U " connected in star, 9, guide rail.
The specific embodiment
As depicted in figs. 1 and 2, a kind of counterweight that is used for elevator of the present utility model comprises counterweight frame, counterweight iron pressing plate 1, counterweight iron 2, short upright beam 6 and horizontal arm-tie 7.Counterweight frame comprises two roofs rail 3, two upright beams 4 and two following side bars 5.Two upright beams 4 are parallel to each other, and vertically place.Two roofs rail 3 are fixedly connected on the top of two upright beams 4, and two roofs rail 3 are parallel to each other.Two following side bars 5 are fixedly connected on the lower end of two upright beams 4, and two following side bars 5 are parallel to each other.Horizontal arm-tie 7 is fixedly connected between two upright beams 4.Short upright beam 6 is between two upright beams 4, and is and parallel with upright beam 4.The bottom of short upright beam 6 is fixedly connected on two following side bars 5, captives joint with horizontal arm-tie 7 in the top of short upright beam 6.Counterweight iron 2 is embedded between upright beam 4 and short upright beam 6.Counterweight iron pressing plate 1 is two, is mobily connected in respectively between upright beam 4 and the short upright beam 6, and is positioned at the upper end of counterweight iron 2.Connection mode between connection mode between connection mode, short upright beam 6 and the following side bar 5 between connection mode, horizontal arm-tie 7 and the upright beam 4 between connection mode between roof rail 3 and the upright beam 4, following side bar 5 and the upright beam 4, short upright beam 6 and the horizontal arm-tie 7 can be common mechanical connection manner, is good with bolted connection still.Use the counterweight of this structure, counterweight iron 2 be arranged as two rows.Like this, under the situation of height elevator operation, can reduce the quality of monolithic counterweight iron, be convenient to loading and unloading.Be divided into double layout, can be fixing respectively with two counterweight iron pressing plates 1, strengthen compressing counterweight iron 2, the anomalous behavior of counterweight iron 2 when actv. prevents high-speed cruising.
Further, be the evenly adjusting of 2 pairs of whole elevator loads of counterweight iron, the distance of upright 6 to the two upright beams 4 of beam of described weak point equates.Like this, counterweight iron 2 is uniformly to the left and right sides both direction that is adjusted in of elevator load in counterweight, can guarantee whole elevator car stressed homogeneity in operational process.
The described counterweight that is used for elevator also comprises two anti-drop blocks 8, and symmetry is fixedly connected on the side of upright beam 4 respectively.Anti-drop block 8 is provided with groove, leaves the gap between groove and the guide rail 9.When normal operation, can not contact between recess edge and the guide rail 9.Under counterweight frame left and right sides offset amplitude surpassed the situation of designing requirement, recess edge then can contact with guide rail 9, produced and counterweight frame skew direction opposite effect power, thereby prevented that counterweight frame from coming off.As a kind of preferred version, as shown in Figure 3, anti-drop block 8 comprises substrate 801 and baffle plate 802, and baffle plate 802 has " U " connected in star 803, and this baffle plate 802 is vertically connected on the substrate 801, and this substrate 801 is fixedly connected on the side of upright beam 4.By 803 designs of " U " connected in star, near the gap restriction counterweight frame position action line of centers of guide rail 9 between " U " connected in star 803 and the guide rail 9.
